I kinda like when there's a regular sized pic, like a thumbnail, with a link to a nice big one. This lets the viewer decide if they want to see the huge pic. It'd be good for people on dialup connections, because I remember my whole computer would freeze if a semi-big pic was in a message.
What I really hate though, is when text stretches off of your screen and you have to scroll sideways to read it. That irks me! :)
mlededee, I love your kitty avatar!
