NextGen Gallery: Learn how to copy or move images between galleries
Sometimes you feel that an image needs to be in more than one gallery OR you mistakenly uploaded images into the wrong gallery. You can move or copy them so you don’t have to start over. I’m using NextGen Galleries from my fine art site as screenshots for this tutorial.
Navigate to Gallery>Galleries and open the gallery that has the images you want to copy or move.
A yellow bar at the top of the page tells you that the image has been moved or copied. The beauty of this is that all your Alt text, Descriptions and tags all go with the image. Nice!
