Added Functionality for Catch Gallery

Would it be possible for you to add the ability to “like” the images in the galleries, maybe with a heart icon in the upper right? Example: I have uploaded 40 pictures into a gallery and I want my mother, who lives in another state, to go to my gallery and click the like button on the images she likes out of that single gallery. I would like to be able to see which ones she liked, perhaps be emailed a list of these likes?

This would replace the need for someone to comment on each image that they like. I would be happy to donate if this is something you could add. Thank you for taking the time to read my question.
