You can pick a wide variety of online photo sharing apps or it can upload to a directory on your PC. (I assume an open share.)

I've looked into this before but it was always a bit too expensive for just a card and some newer cameras have a similar feature so I'm waiting until we upgrade our camera.
During Q4, there are huge promos. Costco.com, for example, has the 4GB Share for $79 and you don't even have to be a costco member to check out (online). BUY.com and Amazon have the 2GB cards for around $50-$60. We also sell directly to consumer, and don't charge S&H (and I realize that there cheaper places to buy the cards online).
In terms of brick & mortar stores, check out our site. We sell at Apple stores, Best Buy, Circuit City, Fry's, Wolf/Ritz, etc...
