cache validation of embedded images

[Dirk Mueller]

Hi, 

I've noticed a problem on some sites, like news.google.com. those set an 
expire date that is way past on the embedded images. currently during 
different actions, we revalidate the image, and reload it as it is always 
expired. that means that upon hovering the images for example, it can happen 
that we trigger an image reload, which is rather ugly. 

I've checked, other browsers don't do that. I wonder what is the correct fix?

only revalidate images when their containing document is loaded/reloaded?

what about image-reloads that are triggered by some javascript action? any 
idea?

how does safari handle validation of inline images ?
