Alex,
images are a separate "page" if you want; the browser issues a separate
request for the image which is only _referenced_ by the page, not
_contained_ within. As such the caching requirements for an image are
unique and absolutely not connected to the caching restrictions of the page
it is referenced from.
That said: if your page is non-cacheable, images it contains will still be
cached if the server allows this.
If you're image tags look like this:
<img src="../images/somepic.gif">
it's most likely the image will be cached (like any other "static" file).
For a tag like
<img src="../imgdb/getimg.php?id=4711">
the script "getimg.php" would need to issue the appropriate cache
directives to allow caching.
