Various features

I’m looking for a WP photo gallery plugin to be used on a website for a Historical Society.
I’d like to know if PhotoGallery by 10Web provides the following features:
1. lightbox zooming
2. user comments
3. if yes to #2, will PhotoGallery user comments appear in the standard WP Recent Comments widget
4. right-click protection at gallery/album level
5. read IPTC metadata (title, description etc.) from image during upload
6. separate image search function (which only searches the PhotoGallery images) with shortcodes
