Marv, you just dealt a Royal by explaining other possible situations that would be totally out of the control of someone using another person's URL to post auction lots. The thought of altering an image that already had bids on it, and the alteration was a similar but much lesser value chip could have any and all bidders wondering what scan was real, what scan was fake, and not knowing who has control (ownership) of a URL, they could only blame everyone involved.

...I hadn't even thought of that possibility when I offered use of my website.

Thanks!
Bob
