Mary - Sounds like a photographer was looking to add images to hers and the interior designers portfolio. By "curating", she meant "staging" as in re-arranging (or temporaily replacig) existing furniture, draperies, etc. in your home during the photo shoot.
Long story short, sounds like she went about things the wrong way. She definitely shoould have offered compensation or a trade arrangement where you get to use a few of the images she photographed for your own marketing. Not necessarily a scam, just a predictably awkward way of approaching a home owner.
