The issue of who 'owns' an image was discussed in this recent thread:
"Who owns a picture?"
I assume you're speaking of the ad Vieux Carre Companions posted on 4-22-12:

If VCC is using images of you without your consent to create the misimpression that you work for them when you don't, and they've failed to take down the images despite your repeated written requests, my advice would be to hire an attorney to send the agency a 'cease and desist' letter. Putting aside the issue of whether the agency engages in conduct in violation of the law in the normal course of business, I would think it's probably a violation of Louisiana state law to use images to deceive consumers.
