I would just love to have the ability to use the images in my various NextGen Galleries as if they where in the media library. I.e I would like to have all the image sizes that my media library images has. I would like to edit the image in the same way as if it was inserted from media library.
It is quite often I have a post with a gallery at the end but would like to use one or two of the gallery images as illustrations to my text. I would the like to have nice image descriptions and everything else that I have carefully crafted in my theme and that works beautifully with the media library.
This kind of feature would also let me use NG Galleries to group images together in some form of stock photo galleries from which I could pick images for use all over my blog. A feature that is sorely lacking in the media library that doesn't allow for any logical grouping at all.
Hope this was understandable and perhaps more people could see the use for this kind of feature. Keep up the incredible work on what is, without competition, the best gallery plug-in for WordPress.
