Thank to all for your answers.

Crop the size of http://www.ursic-ei.si/datoteke/d4.jpg! It's 900 pixels wide, and most of that (half?) is empty and white. Make the image smaller and then use background-position and backgroud-color to compensate for anything you trimmed off the edges.

You have a lot of extra newlines in your HTML source. Not hugely significant, but theoretically - since in HTML there's no practical difference between one new line and two - you might want to remove some.

For images, you should consider a content delivery network (CDN), which will cache your images and other files and server them faster than you web server.

This is a must for any high-traffic website.

On the client, you can multipart download; e.g. in Firefox there's a bunch of settings under network.http.pipelining that help speed downloads.

On the server, there's little you can do (though you can gzip text-based files). The client must just know how to cache.

Since in your question you only ask about the images, I guess you already know that the cost of php processing and/or javascript is minor. If you want to speed up the images you can reduce their size, increase the compression rate... also try different formats. JPG is not always the best one.

Try GIF and/or PNG, also with these you can reduce the number of colors. Usually this formats are way better than JPG when you have simple pictures with few colors.

Also consider if some of your images are a simple patter that can be reproduced/repeated several times. For example, if you have a background image with a side banner, you just need one line and repeat it several times.
