dilemma of cache: two types of image

dilemma of cache: two types of image

People who rely on images to communicate may prefer to cache them  
locally.
however in order to keep up with news, blogs, webchat etc it's  
necessary to ensure the content is fresh.

One workaround is to ensure the server sends a no-cache header for non- 
library content and the browser is set to check weekly.

However not all servers may be set this way, and not all users will  
chose or know to set their browsers.
eg in Opera the relevant cache settings are labelled images and  
documents, and presumably refer to html rather than svg.

for example:
	http://www.openicon.org/iconChat/index.svg
	http://www.openicon.org/feeds/zanadu.svg

Could the working group please consider and comment?
