Displaying latest gallery comments in Drupal block

Hi

I am running Gallery2 embedded in Drupal 4.7 at www.whatsthatpicture.com

I have latest Forum posts, latest news etc displayed in my right sidebar on teh home page, but the one I'd really love to have is a block of the latest image comments (suitably truncated) and then a link through to all the recent comments at http://www.whatsthatpicture.com/?q=gallery&g2_view=comment.ShowAllComments

Is anyone aware how this can be done, or suggest any php code for a custom block?

Thanks, James
