Control image cache - in browser

How do you stop browser image cache loading

[HeadBut]

I want to stop my browser from loading an image from the history and make it go get a new one. My current situation is that I am dynamically creating an image, but while it is being created and transfered the browser shows the old image.

Apache,PHP,Mysql

I think I'm posting this in the correct forum.

Many thanks

Hello, Headbut.
Have you tried to make that the browser do not cache the image? I think I heard that in these cases the server side script can send the browser a header that instructs it to not cache the page.
I hope this helps.
