I was wondering if you could aggregate Galleries into one module. As opposed to having different photo galleries only accessible to that module.

What I am wanting to do is that I have an organisation with different regional operations. They want to display their photos in their parts of the site.

But what would be ideal is if in the front page you could link to a gallery module which aggregated all of the different region's photos aswell.

Is this possible using the existing gallery? If so, how do you do it?
And if not, this would be a really useful feature.

The forums module works in this way. Where you can have a module display only a particular forum group, or all forum groups.
