Glad to hear that it worked out in your favor. That's pretty underhanded of him to steal the photos, not recognizing that they are just as much a result of your labor as the items he purchased from you.
Someone mentioned putting your store name on every photo like a watermark. Sounded like a great idea to prevent something like this happening in the future. I don't know the particulars on how you'd go about it, but definitely something to think about.
