Question for photographers on facebook?

[Chentelle]

I believe that social networking is a great way for photographers to gain exposure and get our work out there. I just opened my business facebook page recently, but my question is this; What is to keep our clients from simply right clicking on the image and saving it, then doing whatever they want with it? Even if the size is reduced and it is watermarked, they can untag themselves in the photograph after they save it and have no further link to our pages. I have also found that younger people now days do not really want actual prints as much as they want the image, so if the image that they like is posted on facebook and they can take it and put it on their phone or ipod to show their friends then why order prints?

Has anyone else had similar issues or any ways around these?
