I'm just installed nextgen gallery and want to use my images in the nextgen gallery for thumbnail and post image in all of my previous post.
I have categories A, B, C, D, E in my wordpress.
If my previous post (such as my last two years post) is in category B i want any picture in nextgen gallery that i categories in category B to be the thumbnail and post image for the post.
can it be done?
