The more I hear about blocks, the less I like them. Newbie user, not developer, and my work is with small, volunteer organizations’ sites, so not a commercially important reaction.

Just a question—what is wrong with using columns of individual images? It seems very understandable, columns keep the images properly lined up, and presumably the images could be whatever shape one wants? Why must there be a single gallery holding them all, why not just have the ability to group them into a unit, as one does on a print-layout page if one wants to move them together?
