If you use Linux instead of Windows on your computer, it can be frustrating trying to use some of the online sites since very few bother to explain what Linux-compatible software is required. Here are some hints and tips which may help:
The Origins Network web-site uses TIFF images, so the "Mozilla-Tiff-Plugin" works fine with Mozilla Firefox or Opera. (Use the '+' and '-' keys to zoom in and out with no limit. Under Windows, you can only get to 100%.)
I use openSUSE version 10.2 on one of my computers so I've tested a number of the online sites.
