HOW TO ADD AN IMAGE AS YOUR BACKGROUND

If you want to use a picture as a background, upload it into a site like photobucket and then take the URL of the picture and go into edit profile and then edit layout and click the edit body and paste the URL into the background image box and then erase the background color code above it and leave it blank. this will make the color transparent. Next go into all the edit boxes in your layout and make the background colors transparent by erasing those background codes. You can re add color if needed by checking how your work looks and adding color back in where needed.
Hope this helps.
