Let visitors favorite images by clicking the star icon and manage their favorite list.

Let visitors write feedback on your images. You can reply to comments and send Emojis for a smooth messaging experience.

Let collaborators directly draw their feedback and ideas on your images using simple annotation tools.

With approval flags, visitors can mark images as Approved or Rejected.

Allow collaborators to add one of five different color labels to an image.

Rename color labels and hide those you don't need. You can also have different labels for each gallery.
