Check out Picasa. It's a Google tool. Photo organizer for your home PC, and with a click of one button, can upload an entire photo album. Set it to upload to at the small size to get maximum # of photos.. By far the easiest application i've found to upload pictures to the web.
Lol, i jsut added'em up. I have over 3600 pics ONLINE through Picasa, one account. I do not know what the max limit is..
@ the low setting of 640x480 avg size is ~ 60Kb. which should be small enough to direct link to any forum site.
Probably wouldn't be able to install the program @ school though. ??
