Flickity carousel images are not loaded completely - javascript

I am currently using the Flickity library to display corousels on my wordpress site.
The problem: When the site produkte is loaded the first time a lot of images get not loaded fully but only the first centimeter.
I am happy for any hints regarding this problem.
Kind regards
Lukas

1) Optimize images using Photoshop or below url and then upload in word press
or add image optimizer api in your word press website

2) Minify CSS
3) Leverage browser caching for the cacheables
4) Minify HTML
cross check with https://gtmetrix.com/ too
hope this will help and boost website performance
Best luck

The most improvement you can get is to optimise the image size to make them as small as possible. Use this online service to reduce image sizes.

You can also install a plugin like Smush to optimise images automatically when they are uploaded.
https://wordpress.org/plugins/wp-smushit/
Also to reduce image sizes in the future you can install this plugin to ensure files of excessive size are resized.

Once you have done this then you can use a caching plugin to speed up you site's overall performance.

Image loading slow on github pages website

I have a simple website created with HTML, CSS and JavaScript and it's hosted on Github pages. But on my site I have like 20 images and when I open my site on the browser it takes a while for the images to load.
How can I make my images load immediately or just faster? Is it because of Github pages host or is it because there are a lot of images on one site?
I have seen websites with more images than that and they are like preloaded or something.
Here is an image
Ways to make images load faster on page
0. Check what's slowing down your page
You can try finding what's slowing it down here: https://web.dev/measure/
1. Compress your image
You might need to compress your image if you don't need it to have so much quality. If you need quality, go to option 2. One website that does this is Kraken. This should allow the page to load faster.
2. Use a CDN
If it still does not work, use a CDN, or content delivery network, to host your images. CDN's store data in many data centers, making it to load data quicker. Try hosting your images in Cloudflare.
3. Make your images smaller
Large images can make your site load slower. So, resize them so they are a bit smaller.
I hope this helps you!

Why does Google include a lot of icons inside their result page's logo? Is it an optimization technique?

A moment ago I found out that the Google logo image of the results page contains a lot of icons (you can see this simply by dragging or inspecting the logo).
I don't think this is a bug so, what's its purpose?
Is it an optimization technique? If so, how it works?
It's called a CSS sprite. It is a performance technique as requesting many small images is costly as it requires a lot of HTTP requests. This only requires one.
Here is a short guide on how to make and use them.
In short: CSS Sprites are a means of combining multiple images into a
single image file for use on a website, to help with performance.

Efficient jQuery or HTML5 image slider

I have a friend that is making a portfolio site. He has some high res images that he would like to display. There will be multiple projects on one page, and several images per project. Because of this, he would like to reduce load time as much as possible, and also conserve system memory usage. That being said, he's afraid that a conventional jQuery slider will eat up too much memory if it's called multiple times on the same page. Also, to load all of the images at initialization is just not an option as this would create long load times. Does anyone know of any image sliders, either jQuery or HTML5, or both that can help with this?
before spending time searching for a good jQuery slider...
...start from the basis:
start following general web design best practices like theese
keep your web page under 100 KB and load fast ? (the more is less the more is better)
use CDN (Content Delivery Network) to store HD images.
load HD images only on-demand, do not preload them.
use compressed, converted (avoid png) and resized images to fit the slider container.
do not scale images with CSS or inline CSS. (neither server side)
make use of the Lazy loading design pattern. (if as you say there are lots of images and the page is going to be very long)

Make site Load Faster

I have 8 MB in PNG files but the Problem is that i cant decompress them anymore i tried every png compressor. Maybe thre is also something in the code? Because the site takes damn forever to load. Is there a way i can compress the javascript or html or so?
Just take a look at the sourcecode and maybe its something there i can do to SPEED it up way faster?
There's like a zillion http-requests on your page. Try reducing the number of requests by using spritesheets and inlining css and javascript.
I see you are also using images for your menu? Try to use a font for that, with the #font-face directive. (this will also prevent the flash you are seeing, when you hover over the menu-items)
And try to use jpegs (as they allow much better compression for photographs in general) for the slideshow. Use a png for the frameborder to allow for transparency. This would also allow much more flexibility, since you don't have to manually add the frameborder in photoshop, should there be more photos to add to the sideshow.
There's like a ton of other stuff you could do to improve your speed. You should try to conform to some of the best practices in the modern web-industry.
Some useful resources for you:
Move the Web Forward
HTML5 Boilerplate
Did you use Photoshop to create your PNGs? If so, did you use File > Save for Web to save the images? That will reduce the size of your PNGs by a ton.
Try running the YSlow addon in Firefox.
YSlow analyses webpages and why they're slow based on Yahoo!'s rules for high performance web sites.
https://addons.mozilla.org/en-US/firefox/addon/yslow/
Things to do to make your page load faster:
Put all <scripts> at the end of the body - this
ensures that initial css and html is rendered before any JavaScripts
is loaded.
Convert you images to jpg. Since your gallery images has no
transparency, there is no need for png.
Resize your gallery images, they are bigger that than needed
Put smaller icons, menu items and other graphics into sprites
Use #font-face insead of servering text as images
Use css gradients for of gradients in images
Compress your JavaScript using tools like UglifyJs
Install page speed for Chrome and Firefox, which measures your speed and rates it and gives you suggestions on how to improve your page's speed.

N.B: You must accept Experimental Extension Apis on Chrome and install Firebug for Firefox.

Reducing image loading times?

I was wondering if there is any other ways to compress my images or any script that would load the page faster / or the the images behind the scenes?
The site is very interactive and using very high quality layers of images for the main layout. I have already saved for web devices in Photoshop and re-compressed using ImageOptim, some are jpeg but the majority are png24 to maintain transparancy, they are all set in CSS.
I have used jpegs and css sprites where i can but there is one in particular of a tree illustration streching the full site length, that is really slowing up the loading time, is there any I could compress these images further or code them differently that I missed?
Any help would be great thanks!
You said you are spriting. That is good.
You can also use tools such as PNGcrush which attempt to make files smaller by dropping things such as meta data.
You should also send far distant expiry headers and use a cache breaker on your images, to ensure the images won't be downloaded again if unnecessary.
In Photoshop, choose file-> save for web, you will be able to find the best compromise between size and quality.
Do you really need the transparency there? PNG transparency is unsupported on some browsers and makes the page processing intensive and slow even on high end computers, depending on image size and quantity of layers. If you can show something of your site maybe someone can give more hints about how to optimize it.
You can compress them on the fly with Apache if that's your web server. One of many available articles on the subject: http://www.samaxes.com/2009/01/more-on-compressing-and-caching-your-site-with-htaccess/
