One of Belarusian contestants addressed me a mail with a question: may they reupload the same photo with a better quality and what consequences will it have concerning WLM.
So, may the participant replace the file uploaded for WLM with the same file of better quality? Will the new file be treated the same as if it was uploaded at the first place?
Besides this, I have a question of my own. Let's say, someone submitted a photo for the contest. Then a random Wikimedian uses it in an article. Then he wants to fix it (colors, perspective, whatever) and actually he does it by replacing the original file with a new fixed version of it. What next? Should the jury examine the original version, or the fixed one? If the photo wins, who takes the prize? And so on.
