Before creating my button I tried many websites and codes that were confusing and didn't work at all! But I found a website that allows you to create your own button very simply so I thought I would share the info with my fellow bloggers.
You may have to re-size and readjust your image first and then obtain a URL for your image. I use tinypic.com and photobucket to re-size and obtain a URL. This site quickly generates the code for you and it's free!
