Botzi,
As a member of the forum for a while, I think you overstepped your bounds with David, who does this for little or no money, and who also is the Webmaster.
I think that you can use all graphics that you want on the web from other sites. I think the point that you are missing is that you used graphics that someone took the time to scan and put on a website for member and non-members to enjoy, and used them for your own services. In addition, you joined the forum also and plugged your sale on Ebay, looking for more traffic on vintage collectors.
I think what is being asked of you is fair, all David is asking is for lack of a better term, a "quid pro quo". You joined his website, used his graphics, plugged your own sale on his site, and then say he is accusing you of stealing? For the record, David stated that you "borrowed the graphics" , not in your words "stealing your graphics." As far as updating the auction, it can be done very easy, since you don't have any bids yet.
Cris, I would suggest that you learn not to "pee in the wind" and open up your wallet and donate a little to this site as a gesture of goodwill, if you haven't already.
I'm sure that David has the capability to handle this, but as a member of the forum I think that this needs to be said on behalf of myself, and anyone else who has contributed financially or grammatically.
