Robinm10,
I suggest using a plugin that can pull in photos from either a facebook photo gallery or from flickr or another photo sharing site.
For flickr, I’ve used the plugin from http://www.slickrflickr.com, and for facebook I’ve used http://www.justin-klein.com/projects/facebook-photo-fetcher.
You are opening yourself up to having any photo appear on your site by doing this. Spammers could potentially place images that you do not want on your site.
Thank you for the comments, esmi.
We are on Twenty Ten already, but I will go through the other ideas and report back.
