When you add photos to an asset, the photo shows up in the Photos menu.
However, if I'm at a client location, for example during onboarding, I may take a bunch of photos, and I may upload them in bulk using the photos menu. From there, it would be nice to be able to go through each photo and link an asset to the photo. Also, it would be helpful to have navigation so you can move through the photos - like "<>" buttons on each side.
