> Tumblr's just not a place you go when you're thinking about buying stuff.

I'll agree that the largest part of tumblr's userbase doesn't have the ability to whip out the credit card at the drop of a hat. I'll argue that TV is also not a place you go when you're thinking about buying stuff, yet display ads seem to be working there.

I'll also add some sympathy for that Etsy seller. I have a friend with an Etsy shop, and the bane of her existence is people reblogging a card or print with no link back (or worse, "google images" listed as the source).

Watermarking images with a name and url is a common practice to help mitigate that problem.
