Do not sign your submission(s) If you want, you can have a look at previous challenges and Vote Challenges are open to any Commons user. Submissions must be your own work, not previously uploaded to Commons prior to the challenge date and should illustrate the challenge theme in the opinion of the photographer. Please read the challenge descriptions, as there may be additional rules or explanations for specific challenges. There is no limit on the number of submissions per user (unless specially so restricted in the challenge), but please choose from among your best and most varied images. To submit pictures, you edit the gallery of the contest and add your candidate(s) to the top of the list. New themes can be proposed and discussed here. Assessment After the challenge has closed to new submissions, the pictures will be assessed by popularity voting in the subsequent month. You are allowed to vote for images submitted by others if your Commons account is at least ten days old and has more than 50 edits or if you participated in one of the challenges. Challenges open for voting can be found here. Winning The best three pictures will be awarded first, second and third place. They will be displayed on the Photo challenge page and may use the template {{Photo challenge winner}} on the file description page.
