I have the following problem.

We have a site. I changed some sprites to make it look cooler. The thing is that we already have users and there is a big chance that their browser have the old images cached. Is there anyway to force a new request to images from them?

Note: On firefox (default settings) after some refreshes the new sprites are requested but seems like chrome (default settings) just doesn’t request them unless you explicitly clear cache.

Another Note: One way would be to rename the sprites but this also means that we have to find them in css files and rename there also, etc. etc. etc.

Have a great day and ty for help.

    One solution would be to add a random number onto the end of the image name e.g.

    .mybackground {
    background-image:url(../images/background.jpg?16549);
}

    If you could make the number random every time the page is loaded via some JS or PHP or whatever that would work for you. YOu could maybe take the images out of your stylesheet and place then in a style tag in your header include or whatever so that you can do the random number bit to them. (Not sure if you could do directly into the stylesheet)
