Prevent Image from being resized using Javascript

I'm putting together a site for work using Wix. Currently, the page I am working on has an image on it that is meant to be used by the user to find out what size of disposable gloves they should purchase.
The issue is this image is resized on computers with a smaller resolution. I need this picture to remain at its exact size no matter what the size of the desktop monitor.
Is there a way of accomplishing this through Javascript?
Layout should be visible by link. Thanks!

You do not have access to CSS/HTML on wix (for this context) so the only way you can control image dimensions is using the fitMode property of the image.

reduce image size and keep it in 100% width

I have some images in my web which linked from image hosting sites. All the images require 100% in width.
However, some images have extremely large pixel and therefore load slow.
How I can set the style to reduce the pixel of images while keep the images in 100% width in order to load faster?
For example, fix the horizontal pixel to 1440px and adjust the vertical pixel and keep it in 100% width?

You have very little control over an image that is hosted elsewhere. Some alternate ideas:
Cache them on another server and load from there
Preload for faster results (which might not work if the image is "above the fold") How exactly does link rel="preload" work?
Use the <picture> tag to specify a different image based on screen size: load images using the picture tag
Load a placeholder image first: How to load a small placeholder image before loading the actual content

you need to have 2 versions of each image, one with the original size and you can use this when user request to download the photo, and the other for the display and the UI, this will make your page load faster and less data bandwidth.

Lazyload images without hurting SEO

We have a product details page on our website and it has a preview of a large image of the product. The problem is because of it being too large and hi-res, it takes time to load and render on our page. Now I've read about something called image upscaling or from what I've understood it works a bit more like lazyloading the images. So the concept is they generate a very small, in terms of file size and image dimension, version of the large image and set it as the initial preview of the image. Then size it up to same as the large image's original dimension. So it is stretched and they blur it out. They wait for the larger image to load then replace the smaller one with it once it is done loading. I've seen this in multiple blogs and news website and it seems like a very good solution. But my concern is, does this affect our page's SEO? If so, is there a way to implement this kind of behavior without hurting our page's SEO?

I understand that you have a problem with optimizing your images. To solve this, I recommend that you apply the following techniques:
Add the srcset attribute to the img element. The srcset attribute extends the functionality of the img element. If the browser does not support the srcset attribute, by default the image file is imported using the src attribute. If the browser supports the srcset attribute, you can specify a list of image sources and conditions (comma-separated) before the request is received. As a result, only those images that match the parameters of the device are downloaded and displayed.
Art direction in the responsive images with the element picture. If you want the images to vary depending on the characteristics of the device (art direction effect), use the element picture. The picture element specifies a declarative solution to provide multiple versions of the same image, depending on the various characteristics of the device: size, resolution, destination, and so on.
<picture>
<source media="(min-width: 800px)" srcset="head.jpg, head-2x.jpg 2x">
<source media="(min-width: 450px)" srcset="head-small.jpg, head-small-2x.jpg 2x">
<img src="head-fb.jpg" srcset="head-fb-2x.jpg 2x" alt="a head carved out of wood">
</picture>
In the above example, if the width of the browser is not less than 800 pixels, the head.jpg or head-2x.jpg format will be used (depending on the screen resolution of the device).If the width of the browser is from 450 to 800 pixels, the formats head-small.jpg or head-small-2x.jpg (also depending on the screen resolution of the device) are applied. If we are talking about a screen width of less than 450 pixels and a device with downward compatibility, the picture element will not be supported. In this case, the browser uses the img element to display the image on the screen (it must be enabled).
Images with relative dimensions. If the final image size is unknown, it is difficult to select the pixel density descriptor for image sources. This, in particular, refers to images that are stretched proportionally to the width of the browser and change their size depending on it. In this case does not indicate the fixed image size and pixel density. Instead, you can determine the size of the image being processed by adding a handle to width. This will allow the browser to automatically calculate the optimal pixel density and select the correct image to load.
<img src="lighthouse-200.jpg" sizes="50vw"
srcset="lighthouse-100.jpg 100w, lighthouse-200.jpg 200w,
lighthouse-400.jpg 400w, lighthouse-800.jpg 800w,
lighthouse-1000.jpg 1000w, lighthouse-1400.jpg 1400w,
lighthouse-1800.jpg 1800w" alt="a lighthouse">
This example shows an image that takes half the width of the viewport (sizes = "50vw" when applying the viewport) and depends on the width of the browser and its ratio of logical and physical pixels. As a result, the browser can select an image that will be displayed correctly in a window of any size.
Please note that images of the JPG-JPEG format have approximately 50% less volume than PNG. Therefore, they are easier and faster to load. To change the image format and resize images, you can use this tool Photo Editor Online. To compress images, you can use this tool - JPEG and PNG compressors.
The best solution is the use of Accelerated Mobile Pages AMP. Please note that in their implementation of the image element is also used the srcset attribute.

You can use for preloading images of the current web page with meta preload, eg: <link rel="preload" href="//examples.com/images/img1.jpg" as="image">

For SEO I'm going to assume you want to go by googles standards for my answer.
lazy loading will help your bandwidth, not your SEO google will judge your website by full page load time.
I recommend you compress your images and that will be all the difference.
if you have any pictures you can load 20 pics and the have a button saying load more, then lazy load from there.
this would be a big SEO boost as your now loading half your website.

Parallax implementation guidance like Sony website

I am developing a website using parallax. Just a brief note on what I did so far.
I used the skrollr plugin for generating the parallax effect. With this plugin I was successfully able to move elements with different scroll speeds. However, there are a few major issues I really to resolve.
Given your understanding and guidance I look forward to get through them.
Here is what I am trying to address:
1) The site that I developed is not responsive with parallax. Data attributes for elements are written inline (and thats how so far I think they are written: inline). So because of that even on screen resize, the inline styling of data attributes remains intact. Hence, the responsive stuff for parallax (on desktop version) is not able to produce same effect on mobile versions.
2) I checked the sony website. Link : http://www.sony.com/be-moved/
They have used parallax and the site is responsive.
Parallax websites are based more on the imagery content. So, how does the site load faster when the images are of huge sizes. (Running into MBs). The sony website has very heavy images (size running into MBs). How do images of such heavy sizes load so fast?
3) Again, coming back to the sony website. On scrolling the user is shown various perspectives / angles of sony products. So, how are the multiple perspectives of every product captured for scrolling.
How is such precise sequential image with varying perspective for every product shown on scroll?
Its the entire background image that changes perspective. So, how is that done? Thats not just plain parallax, right?
I am mentioning this site because its implemented in a differenet way from other simple parallax websites. Sony's implementation is what I am interested in!
4) What would be best to do? Changing background images on scroll(like the way its done on sony) or changing the position of single elements using data attributes?. (like its done on www.numero10.ch)
I have been asked to implement parallax in two ways:
a) only move the elements within the background. Like if its a sky image with two clouds on the right. Then just consider moving the two clouds to the left on scroll.
or
b) Have different background images with the two right clouds moving to the left. So, that means I will have a volley of images for just moving the clouds from right to left; with every image having two clouds shifting towards left by pixel positions.
Looking forward for a reply. :)
Thanks for your patient reading.

I think this will lead you to the right direction: https://ihatetomatoes.net/sonys-be-moved-website-deconstructed/
It explains in detail exactly how the Be Moved website is constructed.

2) I believe they use something called "Lazy Loading" which is displaying a "fake" lighter image until all the HTML,CSS,JS is loaded to then load the real images and replace them.
3) That is not mere parallax , they are using the canvas element ( How exactly I don't know but check the page source )
4) It is better to leave an image as a fixed background and work with smaller elements.

I think that site is not just parallax layered scrolling, It is a combination of a sequence of video clips triggered on scrolling. I have not inspected the element of site but I think so. But site is loading tremendously fast compared to other such sites because of your cache in your system and implementation of lighter images in the starting and heavier images at last

JQuery lightbox plugin: Scaling very large images to fit screen

I'm using the jQuery "Lightbox" plugin, although I don't know if that's necessary information about the problem at hand.
The images I'm putting through my slideshow are quite large; each of them is far larger than the screen (I don't host the images on my server so I cannot resize them). I need to scale them to fit within the bounds of the screen (probably with some margin as well). Are there some JQuery or other Javascript snippets out there to take care of this?
Edit
Now I use "zoombox", which certainly fixes the scaling issue. However, now all the nice slideshow features are lost! I.e., I cannot use the arrow keys or cycle through the gallery of images!

Here are three plugins which are pretty feature rich and widely used, they should do the job with ease :
http://www.jacklmoore.com/colorbox
http://fancybox.net/
http://www.grafikart.fr/zoombox
Edit: Pretty much every lightbox solution is listed and compared at : http://planetozh.com/projects/lightbox-clones/

I've settled on Floatbox after testing out a dozen of these libraries. The default settings size the image to fit the screen and allow navigation with the arrow keys. Clicking on an image zooms it to 100%. It's easily configurable in terms of colors, window decorations, and the like.

I forked Lightbox2 to include automatic scaling.
Now, if an image is larger than the window, it will automatically resize to 80%.
You can find it here, on my new repo.
