is the photo with the copy on it what you showed the customer? if so, that is a really bad idea on so many levels. first off, what you need to do is to have an approval sheet set up that you drop your design onto. on the sheet are the instructions, "no one outside your business is to view design, no part to be copied, ownership of the design belongs to ya da ya signs" put it all in writting, have what you paln to do if they do anything that isn't allowed such as "you will be billed $500" etc, have place to sign and date like a contract. watermark over the design property of ya da ya signs. never give this to them untill a depoist is received. if you want to show them what you can do without that, that's up to you but show them the print out and make them sign off on it and no they don't et to keep it until it is paid for, they only get to see it. what you provided doesn't say it belongs to you. it not only doesn't say that it is just a photo with a layout that could be belong to anyone. you are in business and in business, nothing is left up to the imagination, it is all spelled out in contract form. treat designs the same as any other product.
