It's not hard to do. Once you have the pictures on your computer all yo have to do is make sure that they arent to big. If they are you would have to download a program to resize the picture file. You could prolly google this to find a program. Then login to PetHobbyist, and go to your account and down past your information is something that says post pictures, just click that and the rest is self explanitory, im looking forward to seeing ur tank. I am about to build a custom tank as well for my fast growing burm. only about 7 months old and already nearly 6ft long ! take it easy
