I have it, and love it as well. I just have the lowest tier account, but will most likely upgrade to the pro site as well as soon as baseball season is over. I had commited to the team not to make any money off of the pics I have been taking this season....
i was thinking of doing what JR suggested for next season, and that would help pay for the cost of the site.
Another thought I had was if I am making money, then I can claim it as a business, and therefore write off the costs of any equipment I might buy to the extent I make any profit...
But if for nothing else it is worth the few bucks to me for the offsite storage.
