I am looking for a way to programmatically get all images that have been 
associated with a set of custom properties. Ideally, I should be able to 
say 'give me all images that have key1=value1, key2=value2, etc.

Failing that, at least get all images that have the named keys key1, 
key2, etc. irrespective of their values, so I can filter for the values 
myself.

I was looking at [1], specifically [2], and came up short. Any 
recommendations?
