First off - Welcome to the site! My name is Steph:)
You go to the top right corner of this page and click 'My Photos' which is where you upload them. Make sure of two things:
1) Its a .jpg, .gif or .png file
2) It has a caption
I hope you enjoy the site, if you have any questions about anything around here just drop us a line.
