This application is much better than the pre-loaded photo tool available in the N97. I have not been able to get the latter to view any photos or images I transferred to my N97 from my E71 or PC.
Nokia's Photo Browser application allows me to view, display, zoom and manage my photos. It is nice to be able to scroll through, find your photo, show your friends orsend the photo to via multiple options. Deleting unwanted photos is quick as well.
The only suggestion I would add to make it better would be to add the ability to mark or unmark multiple photos from the grid. This would allow for quicker deleting or moving of the photos as opposed to going one-by-one.
