Question for tumblr people or maybe one C Glass

Example 1, sort of.

Is there a cute/slangy name for when an image blog has repeats?  Like a month later, there's the same golden retriever grabbing the same mallard or what have you.  Do these people not remember that they already used that same picture?  Sometimes it may even be a year before the image repeats, BUT THAT IS STILL NO EXCUSE.

Anyway, there must be some insider-y slang for this phenom and I must know what it is, hopefully by C.O.B. today.
