I've been uploading to iStock, just to get my head wrapped around the process and get myself going on it. Definitely slow going so far. I had registered when I first got this idea with a bunch but never got to the point of uploading, all of the individual tagging and tracking of images seems to be so time consuming. I'm really looking forward to your second post to see more about organizing and working with the multiple sites. Thanks for the tip and I'll get in with some more agencies soon!
