I recently upgraded my wordpress install to v3.5.1, the latest version of WordPress.
I'm running the latest version of the NGG Gallery plugin, Version 1.9.10.
The problem is before v3.5.1, i could go to a Page, edit that page, click Featured Image and select an image from my NGG Gallery and set that image as the featured image.
After updating to v3.5.1, probably because wordpress added many enhancements to the Media library, when i go to edit a page and click set featured image, i can no longer access the NGG Galleries.
Anyone know if there are still hooks to the media gallery for external gallery plugins?
