: From: Warden, Matt
: I'm looking for the ones that would stop caching...
: in other words, have an image re-downloaded
: every time. This is because the image is dynamically
: generated and I don't want the same one popping up
: every time.

lemme guess - webcam.

there's only two ways - meta tags to force a refresh of the entire page or
making the path to the image look different to the browser every time.  the
second is the preferred method.

psuedo-code - translate to your language of choice.

random_num = current time stamp in milliseconds.

<img src="image.gif?somevar=[random_num]">

good luck,
