1. I went to picnik photo editing and uploaded pictures (I pulled 2 fun ones from google images)... had a TON of fun messing around with their photo shop. I resized the image so that it was no bigger than 200x200 (its recommended to be 125x125... but thats kind of tiny).
2. I saved the image to my desktop (you can save it anywhere as long as its accessible to be re-loaded onto the net)
3. Then I followed instructions 2-5 on the following link: click me!
The only thing I did differently was instead of putting it on my sidebar... I made a new page for buttons- as you can see my sidebar is a little overloaded!!!
So there ya go! And please grab a button!!! :)
