The loading animated GIF and the Prev/Next overlays are missing in Lightbox Plus 2.4.6. Tested in 3 of the styles I use: Black, Elegant, and Shadowed. Elegant and Shadowed don't have the Prev/Next overlays like Black does, but in all 3, the animated GIF is missing. Reverting to Lightbox 2.4 restores this functionality. Not sure if broken in 2.4.5. Tested under WordPress 3.3.1, 3.3, and 3.2.1 with 7 different themes.
