Some photo grids display images too small - even when individual images are selected for individual display. We need to be able to change size... even if it only by selection from a list of standard sizes (small/medium/large).

Full-width images are much more likely to be used, if they could be reduced in size where necessary.

It would be nice to have the option (simple yes/no option / radio button) to display photos surrounded by a decent-sized border (similar to a matte in exhibition display).
