Aye, I've been using Photobucket for months and months now...any pictures that are larger than 100k automatically get shrunk down, for bandwidth's sake. /php-bin/shared/images/icons/smile.gif
P.S. - Also, try viewing the picture alone in your web browser, because sometimes the pictures appear smaller than they really are in the preview window. AND (not done yet) sometimes Internet Explorer and Netscape Navigator automatically set themselves to resize a picture so you can see the entire thing at once. You can change this under "Internet Options" in IE or in...I believe "Preferences" in Navigator.
