[Plugin: NextGEN Gallery] set Post thumbnail

Hi,

After making a new post with a NextGen gallery in it I wish to make a Post thumbnail of that post using a picture from the gallery but there is no “use as thumbnail” option.

My steps, make post, insert nextgen gallery, set post thumbnail. It opens the ‘add an image’ screen, I select nextgen, the gallery I wish, show picture and there’s only ‘insert into post’ whereas using a non next gen gallery or direct upload it gives me the option to use as thumb.

Now I must upload an image into the wordpress gallery to set a thumbnail image of the post.

Am I doing something wrong? I’d like to use nextgen for this also.

Thanks
