I think to make any money out of Stock sites you have to put a LOT of pics on them, were talking hundreds.
Thats what Ive been reading too.
If I were to get an idea of photos, maybe several month before the date then I could create a set of photos for say Valentines day or Easter in Jan and put them up on there. Theyre there and they can be used next year too.
Id probably have 50 or so I could look to put up on to a site right now.
