Update: When I press back i get the edit box.
I just installed the wp-jquery-lightbox plugin. When I click on an image in my gallery it opens up a large image preview with lightbox effect and with the ability to step between the images in that gallery.
Thanks @bushbird I’ll look into that plugin instead.
I downloaded “User Access Manager – NextGEN Gallery Extension” and it says “User Access Manager – NextGEN Gallery Extension: Your version of the NextGEN Gallery is not supported. You need at least version 1.7. Your version is: 1.6.2” so I hope 1.7 is released soon.
