You should be able to select multiple photos and assign a common location or tag so they can be filtered at a later stage in construction. Furthermore if you are creating an issue and have assigned the issue a location, this information should automatically be assigned to the photo.
Currently the photo section is not what it should be and clients are taking photos in folders so as to organise them as they wish. This is very frustrating and one I believe competitors can fix easily thus giving them a more competitive edge when choosing project management tools. ACC need to prioritise this in the next update.
