What are you looking for that hitting [[special:random/file]] as many times as images are needed won't provide?
That would give a fair sample, but not necessarily a good sample. the usability folks need "a few of each kind" for testing. getting numbers proportional to the actual "population" of images is unnecessary and probably rather counterproductive.
So, I see two tasks: * identifying relevant "group" of media (along the parameters guillom specified) * sampling from each group
