This plugin is awesome and I've used it on a few sites. I haven't checked up on in the last month or so but my one request would to have commenting / likes / etc connect directly to the photo / album on FB. So if someone commented on the image on my site then it would also show up in the album on FB. That would be AWESOME!
Fantastic plugin regardless and I highly recommend it. I spent the $10 to get the Pro version for a couple extra features, too. Worth it. Five stars if the commenting connected directly to the FB photos :)
