3. Open the cameral roll.

6. plug your phone into your computer and find your phone under the file exploder.
7. Click on the folder that says its your phone.
8. search in that folder using a *. my search field is in the top right corner of that screen.
9. Find the picture you want to put on here and move the picture to the pictures folder on the computer.
10. thats all. Now you can upload your picture on here by finding it in your pictures folder
