If you follow this link (https://www.chameleonforums.com/january-2014-photo-contest-123125/) you can scroll down a little past the information and you'll see a link that says "enter contest." At that point you just upload the photo and voila! Entries close on the 19th so you have a few days left.
If I could offer a tip, choose a photo where you don't have windows and things as part of the background. It's more likely to be chosen for final voting if the background isn't distracting.
