Thanks, Brianetta. I understand that, and have tried, nothing seems to work.BobBill, that's the problem. Your pics, your property, and Wikimedia has absolutely no right to publish them unless you allow it. Bear in mind that their site is syndicated, and can be published in print. If you don't license your work to them, such that they can re-license it, they can't do a thing with it. Their only option is to refuse your upload.
