Never load anything to facebook ever that you ever want to use for any commercial purposes.
When you upload an image to facebook, they get an unlimited license to resell or distribute or modify it any way they want. Which includes letting other users repost things. Once you uploaded it to facebook, you actually didn't own exclusive copyright on the image anymore, so it wasn't, in fact, necessarily illegal for the bride to repost it, and there's not necessarily anything you can do about it (facebook could stop her if they wanted, but not you).
Facebook could even sell your photos to an advertising agency and put some advertising text and a logo in there in the corner and plaster it up on a billboard to sell Coke. And you couldn't do anything about it. Etc. etc.
If you must post things online, use your own website, or some site that doesn't claim a license on your work, like Flickr, and ALSO watermark and/or reduce to a uselessly small resolution for printing (<1000 pixels long edge)
