use Netscape on my PC in Windows 95/98 and I just put my cursor in the
middle of whichever picture I want to capture and right click with the
mouse. I get a new menu that has "View Image" and "Save Image As" among
other options. The "View Image" selection also shows the file name I gave
the picture. When I select "View Image" I get a new page with just the
picture I've selected displayed. From here I can print the picture or save
it to my computer. The "Save Image As" selection only allows the option
to save each individual photo to my computer (something that can be done
from the "View Image" selection). Both choices use the resolution the photo
was originally uploaded at. I have run into a problem with "AOL" changing
the photos' resolution to something really low when we tried saving them
with the "Save Image As" selection. I didn't try using the "View Image"
I think all you have to do on a Mac is put your cursor in the middle of the picture you want and click and drag it to your desktop and either print or save it from there.
Incidently this will work for almost any photo or icon you see on the web that you'd like to copy.
