Question

This time my setup looks like this: one table with galleries names

CREATE TABLE GalleriesName (
    gallery_id
    , gallery_name
) 

and another table with galleries photos

CREATE TABLE GalleriesPhotos (
    photo_id
    , photo_gallery_id
    , photo_name
) 

What I need is to get all the galleries with one random picture for each gallery.

Is it possible to do this with a single query?

Yes it possible. you need to learn to make SUBSELECTS with mysql. Just select a gallery then subselect a random image [ with rand() ] with that gallery ID =)
