Hello,
I'd like to suggest a feature to make this plugin more user friendly (some clients of mine are not comfortable in writing some basic html..): Choose not to display exif data on a specific image by flagging a "no EXIF" tickbox in the img dialog that inserts the hk_noexif class in <img>.
I'm not a programmer, so please forgive me if I'm asking too much!
BTW, your plugin is really useful, Thanks!
