Great piece here by Christopher Testi on his experiences selling images on several micropayment or microstock sites. Two things to note:

1. Testi indicates that his better work never appears on micropayment sites - this refutes what many on Wall Street are saying that user generated images will destroy higher level image sales.

2. Stockxpert - the Jupiterimages entry in the micropayment arena comes off very well in comparison to the competition.
