you created a kewl plug-in, hat off! :-)
Version 1.1 is showing up a few issues under WP 3.5.1, as it seems the prefs are not respected properly (e.g.: deactivating the "Show Permalink" option or "Show Thumbnails" option does not work, activitating the "Show description" option seems also not being functional at the moment).
Apropos prefs: It would be very cool if you could add a pref for disabling image title, too. I guess most of the people are uploading photos from their cameras that have generic titles like "Image_1234", which is not very sexy on a website. :-)
Another suggestion: Would be mega cool as well if you could add a pref for activating native fullscreen mode automatically, so website visitor interaction (pressing 'F' key) is not necessary anymore.
Keep on the great work!
