Can there please be a picture height and width maximum for this site when posting pictures?

Lately I've been finding I have to scroll over in some threads because the pictures are far too large! And it kind of gets annoying..

Seeing how most people and default settings on most computers, their viewing at 1024 x 768.. I don't think the width of the picture needs to be bigger than 768!

Sorry if I'm sounding naggish, but I like it when I don't have to scroll horizontally to see pictures! (Plus, it takes longer for them to load! )
