A line like that is something that could be considered, although I am worried that it would become an empty field, since people don't seem to be as worried about a card's gallery position.

And yeah, the gallery templates are a bit difficult to use. Basically, pictures are linked by name, so to replace a picture, simply upload a new one with the same name so it overwrites.
