Number of pictures on a Free Site
 

What is too many and too little amount of pictures to be on a free site?

I have been making all sites in the past for people with an index, main gallery index, and 2 gallery pages with 5 pics on each gallery.

Is this the average and requirement for most link lists or are their link lists that want different?

That's another "read the rules" kinda thing - most places ask for 20 pics total with 10 per page.
