We've created a Flickr group for the Austin Film Festival where we'll be sharing our own snapshots of the 2005 Festival, and where you can upload your photos as well. Right now you can see pictures we took today of some of the staff. If you see them around the Festival, be sure to tell them you saw their picture on the Internet.
Flickr is one of the best photo sharing services on the web, with free memberships available (though you can upgrade to a "Pro" membership if you want to share lots of pictures). Once you upload your pix, just add them to the Austin Film Festival group photo pool so everyone else can see them! While there you can also use Flickr's discussion features to leave comments and converse with other attendees about the Festival.
