I've tried to decrease the size/quality of my background picture, but still it loads rather slowly.
I often visit sites that have much higher quality backgrounds that load instantly
my site: http://staging.tabler.io/
How can I speed it up?
Your image is 1.1 MB so, contrary to the filename, it's not optimized. Save it as a smaller file and/or optimize it with an app.
Also remember that the browser will cache the image.

I know reducing your requests to the server will help reduce load time. Placing all of your images into a sprite can really help with this. However, when is a sprite too big?
The sprite for my page is 1.7mb! I thought about splitting the sprite up into smaller sprites. That will increase server requests and would seem to be a pointless task.
My site loads too slow and I’m trying to pinpoint the slow downs.
Can anyone suggest how should I handle one big sprite? should I break it into multiple files or is there any other suggestion to improve the page load time.
The best size is 4096 x 4096 What is the maximum sprite sheet size I can use for android devices?
So long as you are using fewer pixels than that, you should be fine. The only logical reason to break up your sprite images smaller than that is if you want to give the user an image to look at while they wait for the others to load. (Or if there are some images you know some users will never see on their visit.) But it will increase the loading time overall.
As for file size, add compression to your personal taste. If your hatred of the loading time and your hatred of the compression artefacts are equal, you have found the right balance.
My site is taking a long time to load. It is quite resource intensive but upon checking a waterfall of the site load I have two images that take a very long time to load.

I have scaled the images in the WP media image editor so that they are a reasonable size but the waterfall still shows long load times on those images?

Any insights are appreciated!
Though you resized the image in wp, that doesn't really change the file size. I downloaded your dark banner photo and it was 12.8mb. That's huge and takes a long time to load. Try and get your images around 500kb or less. It should still be pretty clear at 200kb even. It will still have decent quality at those levels. Your image size is also huge, at 1920X3000. Definitely doesn't need to be that large. Check out this link for a rough idea of sizing: Image sizing for background images
I'm really confused with this one as it seems impossible to do.
When running my site through GTMetrix I pass great but with Google page speed insights it's insisting my images can be optimized more for instance:
Compressing and resizing mysite.com/…ets/img/homepage/my_image.jpg could save 78.5KiB (94% reduction).
The image in question is 65KiB so how Google thinks I can shave another 78.5 off it I don't know.
I'm using jquery unveil and using the retina function on it too could that be the problem?
Also I've tried downloading the images Google provides as their compressed version but these images have had their dimensions changed so would look terrible if I put them at their intended size.
Really confused, any help would be appreciated.
Thanks
There are few things you need to distinguish before proceeding with optimizing images for Google Page Speed.
Images are optimized for different platforms (Desktop and Mobile)
Images are optimized for physical size.
Reports for images can be "Compressing and resizing" and "Compressing" only. Compressing means u need to do a compression part, on other hand compressing and resizing means you need to use appropriately sized image for appropriate platform.
Depending on the report you are looking at (desktop or mobile), your item "Compressing and resizing mysite.com/…ets/img/homepage/my_image.jpg could save 78.5KiB (94% reduction)." needs to be less in dimensions and compressed or just less in dimensions. Margin for resizing an image with CSS is around 20% so if you got 100x100px image you can resize it to around 120x120px with CSS without getting report on that item (that is if you also optimized it physically also). To check this in Chrome, inspect image and check "Natural" size in element selector.
You can deal with this on few ways:
Media Query (note that you have to use background image in this case)
Srssets
JS
Depending on the image compression package that you use, you might get different compression results. I've noticed that sometimes Google's Page Speed is able to optimise an image further than I have been able to (and other times not!)
Do you have a live URL for your web page? Or even the image? It helps to be able to see it live and compare!
I have a colourful background image that is 2000px x 1500px and because of the details I am saving it as a jpeg that renders at 1.1 MB. I am using the CSS background property to render the image. So being relatively new to web dev and working with a client/designer that's not open to a change of design at this point in the process, what should I do to help this image load blazingly fast. I don't know if it makes a difference but the site is using Joomla 1.5.9. This is something I've always wanted to understand but have had trouble uncovering solutions for... I hope someone can help!!
Thanks everyone!
There's no way to make images magically load faster. Sometimes, though, splitting an image in smaller images allows for surprising size gains; so if it's not out of question for your CSS layout (it typically is, though), you could try this.
Another possibility for you would be to use progressive JPEG images. They are encoded in such a way that enables browsers to display a progressively more precise image as it loads. This means that at first, the image appears blurry (or incomplete) but with full-dimensions, then it progressively gets sharper and better. It's well-suited for images meant to load slowly (or at least, images acknowledged to load slowly).
The best thing that you can do is try to shrink the file size to as small as possible. Let this be using some type of optimizer, smush.it for example. If you created the background image try saving it as progressive first, it loads a lower res version first then finishes loading. But the best thing is to try to shrink the size of the image width and height by finding a repeating pattern and cropping just that portion out and using it. Most about.me images are no larger than 100kb in size that are above 1200px wide.
you could immediatley call the image in the head by using
<script>
(new Image()).src = "IMAGE PATH";
</script>
and make sure you compress the image as much as you can with different programs, or if you have photoshop cs5 you can save it for a web device to strip out all of the extra junk, you can try yahoo's smush.it
http://www.smushit.com/ysmush.it/
or you could delay the loading of the site entirely for a few seconds, until you can be sure that the image is loading, you could try something like hiding all of the elements and fading them in upon a setTimeout something like
*CSS
body{
opacity:0;
}
*jQuery
setTimeout(function(){$('body').animate({opacity:'1'},300)},5000);
although that may not be all that practical.
Would loading the background image after the rest of the page has loaded work for you? At least this way visitors will be able to use the rest of your site until the 1.1MB has loaded.
Something along the lines of setting the style attribute of the <body> to be background: url(image.jpg) within an onload function?
Delivering the image over a CDN will likely speed things up; the better ones are usually optimized to deliver the proper TCP packet size/MTU to the wide variety of clients out there and have generally done a lot of work in the details of delivering things quickly. Slow connections like cellphones will still hate you for it, but getting things like packet size right can make the most of the bandwidth that is available.
I want to put images of the 1024x768 as backgrounds and load quickly using css. I could use
background(url....)
in the CSS, but will that solve the issue, of downloading images quickl?
Thanks

If you have to use this technique, then remember to compress and cache the image, this will speed it up somewhat, but try and be creative with alternative solutions.
For example can the background repeat on the x-axis? If it can you'll be able to create a 1px wide version that you can repeat across the page.
Try searching for this. It helps cutting off a few KB of data. PNG Gauntlet is also a free software for PNG compression that also cuts Gama correction that causes problems with IE6 and IE7.
Body background images are usually saved with lower quality, thus reducing size.
If your backgrounds are changeable, preload them. It is done by putting divs of zero height at the beginning of the page, and assigning background-image style to each. The images are loaded at the beginning, so when the background of the body gets changed the user doesn't notice the lag.
Google started to count the load time already, so classic preloading causes problems with SEO. Loading with JS, after the page fully loads is an option, or even assigning styles with JS after certain actions are made is also a solution.
remember you can't change the user dsl speed. so css background would be good. Maybe start with take a higher JPEG compression to minimize the file
(btw. i hate (full size) background images at websites with my dsl light)
