For those users that want to be able to resize their own pictures for posting or for avatars, here are a few programs you can download which work well.
For WinXP users: XP resizer Just scroll down to the Image Resizer download link. It's probably the simplest, fastest way for XP users to resize their images.
http://bluefive.pair.com/pixresizer.htm I haven't used this one, but another board member has recommended it.
Lview Pro Choose the 21day trial version download. It still works after 21 days, but is slower to load after the trial period. I've used this in the past, and it's a decent program.
In general posting, a 640 x 480 image is a good fit on the board. Large enough for decent detail, small enough that users shouldn't have to scroll sideways to see the whole image.
For avatars, maximum size is 150 x 150 pixels.
