[FR] add options to limit photos selected

[TomW1605]

this looks great but i would love it if there was a way to only pick photos from a set list of albums

my library has a lot of random junk in there i dont overly want displayed so it would be great to give it a list of all my holiday albums to pull from (or make a smart album that has all the holidays in it if only pulling from 1 album is easier)

i have had a look at the code and i honestly cant work out whats going on with the photos DB access
