Gallery - create many albums using a selection of images from the same base stock?

I am building a site that will have a large number of image portfolios on it which will continue to increase. Most portfolios will draw on a selection of images from the same base stock of images (just different combinations each time, number of images can vary but average 25), so I don't want the client to have to upload images again each time they need to create a new album.

Is Gallery a solution for this?

I think gallery has its own upload-folder for each album, not sure, if there is a way to reuse uploaded images from one main-folder.

One way could be to use the MIGX-TV to create the portfolio-galleries.

Thanks for your reply, Bruno. I am playing around with image tags at the moment and that might be a solution. Not sure yet how feasible it is for the client but it could work.

Any other suggestions still welcome. Thanks!
