Plugin provides several shorttags for displaying image galleries and single images attached to post as attachments. It also allows to group post attachments into several sets that can be used to generate galleries for subset of all attached images. I wrote this plugin since I wasn’t satisfied with standard [gallery] shorttag – I had to do many workarounds and hacks to have it working according my needs. Shutter reloaded is integrated, but plugin can be used without it (with lightbox etc.).
