I don't think a checker exist. and i have no idea if any challenges like that exists or are allowed, Only way to know that i to try to publish one
I am writing a checker that uses the badges and if you set the requirement on the same values at the "The Shutterbug" badge it will be easy to use.
It is possible to use any number of images uploaded but my current code cant check for that.
The checker will probably be completed this week
