Image Moderation question

Im not 100% sure, but I think your moderation for a certain image is only counted once, after that you have to wait for a certain number (not sure how many) of other people to approve/disapprove for the image to leave the queue... (apologies if all that is a load of rubbish)

A certain number of people have to dis/approve an image before it leaves the moderation que. While you may have already approved the image it hasn't left the pending images because it still hasn't reached the threshold number of users needed to approve it.

If the images are repeating, there are no images left. Feel free to stop moderating.

@LordAndrew: 
That's not necessarily correct in my case. I've found images I had yet to mod by skipping through all the previous ones 
but they are few and far between. And when I dis/approve a couple, it seems to take me all the way back to 
the images I already have made up my mind about.  
 

@creamypies:     

That's a glitch then. Not much you can do about that. Just take a break and go back later after someone else has spent some time moderating.
