I did as you suggested and hit the refresh button on N7. The .gif did 
*not* display. I guess that is the proper behaviour?

The php page was not changed, just the gif.

I know the browser probably checked with the server to see if the php 
page was still valid (and found it was), but do browsers normally check 
to see if the images in the HTML are still valid too?

Either way that does not answer my question as to wether the image had 
been cached in the first place. All I know is that the browser did not 
use a cached copy of the image (possibly because the server told it the 
gif was no longer available).

How can I test that the image *was* cached, *and* that the cached copy 
is used when it the server's version has no been changed?

Thansk again!
