free sites content and getting listed

[Roni20]

hi

i bought some content pack , have sets for 30 pictures and have question what is the best way to put them in galleries on free sites

1) 2 galleries with one set , 15 pictures on gallery

2) 2 galleries with first 15 pictures from first set and first 15 pictures from second set , and after all sets put pictures not use in first submit so second 15 pictures from first set and second 15 pictures from second set

or maybe is better way to do it?
