Pictures should have a Photo Count filter available for photo galleries the same way that Videos have a duration filter.

There are some galleries that have Hundreds of pictures. And then there are galleries which only have one picture or a handful of them.

I like being able to scroll through pages of pictures, all related to the same theme - - so I would really like to have the option to set a minimum count for the number of photos.

It would also be good to have a maximum, for anybody who wanted to limit the size of the galleries they looked at.

The intervals id suggest are
Any Number
15 pictures (up to a single page)
40 pictures
100 pictures

Set as either a Minimum or Maximum

This would be really easy to implement because all the search code has to do is omit galleries that have a photo count which doesn't match the Max/Min threshold.
