These headers only work for the HTML content of the page. GIFs are still
cached regardless of what headers you put into the page as far as I know.
The only way you can avoid from having your gifs cached as well is
to write a php wrapper function that outputs the gif so you could use an
<IMG> tag like this:
<IMG src="/wrapper.php3?img=something.gif&dummy=<? echo uniqid(""); ?>">
This way, you can avoid from having the gif cached since uniqid("")
outputs a different result every time the page is loaded.
