Here's a PIC of it I hope I've done this right. I'm having a hard time figureing out the resizier. I'll get it right in a year or two, LOL
Edit: I resized it for you.
Ok guys this is too easy.
In your photobucket account, right where you upload pics is a button.
It is called "options"!
Click options and set it for "15" screen (800X600)"
Set it to that and photobucket will automatically resize ALL of your pics to the 800X600 size.
