but 'tis better to teach a man to fish, and all that. Open Firefox, then Tools>Live HTTP Headers, which will open a separate window. Now navigate to the site you want, and click on the image. As it blows up into something big, the Live HTTP Headers will record the image location. Copy that location, and paste into a browser. (You may need to scroll back up through lines of other junk before you find the image location. Look for a ".jpg" line)
Many sites use .swf files for their images. For those, copy the location, paste, and then manipulate the line. Begin by changing the swf to jpg. You'll often have to change the image parameters to something like "rect=0,0,1000,1000" and "scl=1.5".
Some sites use tiles instead of whole images. If you have the patience, you can paste them into an image editor. I have not found a tile site that will also fork over the image as a whole at hi-res.
