I just got through 24 pages of forum posts, and I think I can safely say I did RTFM :)
When I create a page with an album like this;
I see the galleries contained within the album and that's good. Precisely what's needed. Then things become strange;
Clicking on the gallery produces a vertical "listing" of thumbnails, which although it does the job of showing what's in the gallery, it's ugly....
Initially I thought it was the theme to blame, but invoking the default theme (assuming that does everything perfectly, and useful as a test if the theme is suspected to be causing problems) I got the same result.
Both are pleasing! It would be - I suppose - an even greater bonus to be able to specify how many columns/rows on a page....but that's probably way too picky. I'll gladly settle for 3 across and 2 rows just exactly as seen on Alex's pages...that's just fine for now.
An example of what I'm carrying on about can be seen here (hint, it's not pretty!): http://www.dogshit.eu/?page_id=297&album=2&gallery=2
