Dynamic images, preventing cache from the page that generates image
<p>I have one page that generates png images on the fly,project is not over yet so I didn't test it but I can assume that I will have problem with images chaching.</p>

<p>The images my page generates will be used mostly on forums, as signature. Since no code is allowed except some BBCode(images,links) Im not sure is it even possible disable caching from my page that generates image?</p>

<p>I can already imagine situation: User puts img tags in his forum signature leading to my page that generates dynamic images for his signature. When he first opens page, his browser caches image, and each time he opens that page even if I stream different image, he will see the old one?</p>

<p>Will that really happen, or did I assume wrong? If this does happen, is there any way around it?</p>
