I've installed the file gallery plug in, as I wanted to be able to have multiple galleries per page. This works great!
The question I had was to how to get a box/frame around the images on the page, so they look a bit more finished and so it's not just a picture plonked on the page. I've added the word thickbox in the link class box, both under Insert a Gallery and Insert Single Files, and thickbox is also listed in the Auto enqueue lightbox scripts for which link classes (separate with commas)? under File Gallery in media settings, but still nothing.
Any help greatly appreciated.
