As far as grabbing pictures, I have found that LWP::Simple will get them as it apparently ( and someone please correct me if I'm wrong here ) grabs the entire page, code and graphics.
I will correct you on this one. :)
LWP::Simple does *not* in itself grab it all. If you point it at a HTML page, it will grab the HTML. If you point it directly at an image, it will grab the image. The HTML may contain image tags (something like: <img src="image.gif" />), and browsers will automatically follow the urls given there and fetch the images too. LWP::Simple will not - if that is the way you want it, you will need to parse the HTML for those URL:s and continue to fetch. Or you use an already invented wheel, like Image::Grab suggested by wil above. :)
You have moved into a dark place.
It is pitch black. You are likely to be eaten by a grue.
