Everyone has talked about multiple entries of the not-so-perfect images, has anyone thought about what it would be like if the "Bryce Greats" entered multiple entries. I think I can say that they would all have the integrity and humbleness to not put in more than one entry even if allowed. But still. Without my mentioning their names, just picture trying to create an image able to get just a vote or two up against them. And them having entered 2 or 3 images apiece.
It is already difficult enough creating a good image. Something like that would completely take the wind out of my sails.
I vote C: Never allow - but allow a person to change their uploaded picture if they feel they have a better image or have made some good progress with the one already posted. (It would be better to wait closer to the deadline, but some people feel the urgency to get upload as so as they can. So if it is doable, allowing a change of mind should be accepted)
