Found this Send to Flickr bookmarklet on Lifehacker. Just what I wanted to be able to send pics from web pages straight to Flickr.
Of course, you could alternatively check out the superb Clipmarks!
Clipmarks is a tasty site that lets you grap a chunk of a web page or from different web pages as you're browsing, and then send them (or 'clipmark' them i guess) to your personal Clipmark store, which of course can be shared with other users!
I'm really linking this right now. Go check it out :)
