Sitewide gallery with multiple users

Hello. I am building a directory website for professional photographers using the MyListing theme. You can see the website here: http://www.pnwportraits.com. Photographers build their own listing page and upload images to their gallery. Right now, their images are only viewable from their specific listing page. I want to create a sitewide gallery where site visitors can browse ALL the photos from ALL of the photographers at once. If the site visitor clicks on a photo, they can see the photographer who uploaded it and visit their listing page. I also want search/sort features by category or tag. Is this possible with your product?
