I'd caution that some of the statements being made could be considered libelous if these images were legally purchased through said service. If that stock photo company does not have the legal right to sell the photos in question (i.e. Lanny didn't post them there nor give that stock photo company permission to sell his photos), then it would be the stock company's fault.
Not to complicate it further, but the stock photo company could also be covered under the "safe harbor" rules of the DMCA (if their user agreement places all liability onto the offender), in which case the only party responsible is the one who uploaded Lanny's image(s) to the service.
Also, it's up to the infringed party (not the offender) to take action to protect their copyright, which can include filing a DMCA complaint.
