Allow comments for images?

Is there anyway that visitors to the gallery can be enabled to leave comments on the images?

I’d like a comment box beneath each image as they are clicked on to enlarge.

If Lazyest Gallery can’t do this, does anyone know of a gallery that can do this?

Also, can you add tags to images so they can be searched from the WordPress wite?

Thanks….
