• Click on Enter Contests/Upload Photos. It's a small button in the light green stripe (top of page).
• Click on Browse ... and navigate to to the image you want to enter. Keep in mind that images can be no larger than 3,000 KB (3 MB). You can upload as many as five images at a time.

• Click on Continue
• When upload is successful, click Continue.
• Move the Select album box to specify the contest you want to enter.
• Provide as much information as you'd like about your photo. You don't have to fill in all the fields, but you should at least give your shots a Photo Title and Photo Description.
• When you're finished, click Continue.
• To see the album after your photos have been posted, click Album List, which is a tab at the top of the page.
• From there, navigate to the contest you entered and you'll see your entry.
