thumbs to full sized images

I do not even know what to ask for, ie, I don't know what these programs are called. What I am looking for is a program that will take all the thumb nails on a page, and download the full size images that they are linked too. Hopefully this program would work for all pages. And oh yeah, it'd be real nice if had no malware and was braindead easy to operate. This is the best place on the web to ask so I thought that I would ask here.

 

Well you could look at these:
