Is it mistake?
 

If i put 4 galleries on free site and in every gallery 5 pictures?
( Sorry about English hope that you understand what i'm trying to say )

It depends on where you submitted it too, but most do like to see two galleries min of 10 pics each :)

You might run into the # of pictures per banners on a page ratio problem..

Most places have a minimum number of pics per galery page rule, so you'd have to read the Link List's rule before submittting to them.

For me, I require at least 10 pics per page, so I'd decline it :(
