Maybe using flexgallery incorrectly, but I created the first row, no problems, saved as a copy (2) no problems, margin padding or at least what I call as padding all around the pixs ok. Then saved as copy (3) now I have no padding between (2) and (3). Even Changed margin padding to 50 with no effect.
(1) is Top 1a, (2) is Top2a (3) is Top3a I thought that it might be the size of (3)s pixs, so put (1) there with same results.

In another thread, I asked about killing the little box in the lower left corner.

Thanks for the time.

More info: I see that I can go into module modification and add top padding, but I don't think that this is the right way to solve this.

update: Realized that in the Template Module container width I had turned off padding, what that did was put padding between (2) & (3) it also made (1) wider than the others, but at least I figured this out. I will use module modification for now.

Hopefully this will help others.
