How many views must an image have before people can comment?

Title says it all, I have over 300 views but nobody comments... 
Only images in the gallery can be commented on. Images go into the gallery based on view count and overall popularity all over the Internet (links to it, etc.).
But how many does it take? My photo has over 50k views and it's still not able to be commented on.
