Click on "Go Advanced" below and down at the bottom there is a button that says "Manage Attachments". Then browse your computer till you find the image file and click upload. Good luck! Can't wait to see your turtle.
Right now he is in a 20 gallon long turtle tank but I have a 40 gallon breeder that he is going to be moved into. But when im home he is in a kiddie pool in the basement with me.
