Step 1: Here is a picture I got from my camera (I am assuming everyone knows how to get them from there so I will not go over that since cameras vary so widely.) Find it.
Step 2: Most pictures from cameras are too many bytes (the best size for pictures to be is around 100mb) for the forum to upload. Therefore you must resize them. I use Photoshop CS this being an expensive program I will list a free and slightly easier for beginners. OPEN PAINT this program comes on every pc.
