I've been Googling around the internet oceans in search of a piece of
code that has a similar functionality as the Digg image fetcher. I've
always wondered how this thing works exactly.

The thing is, you give it a URL. It then crawls the site for images,
and gives them to you in a nice tidy way, with a ay a radio button
next to each image. You select the one you like/want, and it discards
the rest.

I just want the image fetcher, the rest is not that difficult. Oh and
I don't need the whole code, just some general pointers to what I need
to look for exactly.
