Start by clicking on the email. It's underlined.
The subject should be "PureiWeb Art".
Add an attachment. If you did some digital art, it should be in PNG format so it looks nice. For art done on paper, take a really nice photo. Or if you have a photo/document scanner, use it! If your device takes PNG photos, make sure it's set to do so. But if your device can't do that, JPEG photos are just fine. It's okay if your camera is blurry, but make sure it's not THAT blurry where you can't see anything. You can borrow a friend or family member's camera if you have a super blurry one.
Send the photo! Don't forget a description if you can!
