every digital camera i have ever seen comes with a photo editing program on the cd you can use that program to resize your pics before uploading them onto the server if you resize your pictures to 450 pixels wide they display great in posts to find out how to resize pictures with your photo editing software try clicking on "help" in that program or open the program and hit the F1 key that brings up the help directory in most programs.
as for those that find the wide pics thing intolerable i would recommend downloading installing and using mozilla firefox this browser will automatic resize those huge pics so they fit on your screen.
huge pics are the scourge of every discussion board that allows pics.
all the admins could do with the current software is limit file sizes allowed to be uploaded then no one would be able to upload pdf files or mpeg movie files or any of the other cool stuff that we can now. it would probably also cause a firestorm of complaints from users that they are unable to upload pics, accusations of discrimination and hatemail. that would be a royal mess.
