It's easier for me if you just read the whole story here at my blog:

The best part is how Sylvia didn't believe me--not one bit--but I am quite skilled at spotting my work even at thumbnail size so there was never a doubt in my mind. She's seen the proof and has come around...
In fact, the photo in question was always at the top of my short list of pics that were likely to be ripped-off.

Hi Alan, this photo has been stolen for commercial purposes, this is so bad and not right, but I'm glad you caught this, otherwise how would have been known this... They have to contact with you for your permission, but what could be done more for them, I don't know, for example copy rights etc. Sorry to hear this, by the way I should say this too, it is a wonderful picture and I haven't visited before your (blog/flickr) photos, they are so beautiful.

Blessing and Happiness,
with my love,
nia

I would hit them with a cease and desist notice immediately, then offer to allow them to avoid further legal complications and continue to use your picture with a payment of $500.00.

Not a huge amount but low enough that they may well pay it just to keep the peace and avoid any further legal action, even if you have no intention of taking it further.

I had a similar thing happen 2 years ago, I requested tehy remove my image or give me credit for it's use, they did neither. I sent a registered letter to their websites hosting company (trace route is great if they are not on their own server) and told them as they were hosting my copyrighted image, I was suing them. The website was taken offline the day the letter arrived at their office. The company eventually got their website back online, but my Image was removed.

Yup, it's Big Honking Watermark time.

I'd be sending them a bill for the commercial real estate site - or a business card, but real estate people do tend to be frugal, and it's hard to compete with "free".

But I'd certainly be sending a great big infringement/takedown notice to the people who put that quiz on Facebook. The FB terms and conditions, found here, read (in part):
