NextGen "Gallery Preview" When Creating An Album

Hello,

I was wondering if I am overlooking something in the NextGen Admin or perhaps I am having a .js conflict? When I create an album by assembling galleries, the image that is displayed as the preview image for each gallery is not the desirable image.

I have tried sort order (the feature to sort the gallery), re-uploaded my images to either get a larger or lower id, and so forth.

Does anyone know how Nextgen is calculating what image to use? or how I can over come this?

I am using WP 3.1.1 and Nextgen 1.7.4

Thank you.
