Ok, just thought stuff had updated in the last 15 years or so
when I did free sites and galleries in '99 early 2000's I could see why it was all about the traffic, now days it should be more about content quality and a link for seo. Your sites though so your rules
For me it makes more sense to get more links to a gallery so i can try and seo target some longtail keywords with each gallery, that will be hard with 3-4 recips since the link power I get to that gallery will not be enough. It is what it is I guess
