Facebook, security and watermarks

As stated in my last blog, Watermarks, this also applies to Facebook pages that I promote artists and their work, there is an alert on Facebook pages when someone downloads a picture and they have to get permission off the holder of the works, but on Facebook that doesn't always apply some items do slip through the net on there. Watermarks on the works will inhibit viewers with stealing the work in mind, also there is a limit of the amount I can promote on my Facebook pages as it does tend to crash when too many different people's photos are passed on as they do have considerable high resolutions, that's probably the basic cause of the problem. There is also a closed door on security, which is good, too many cross references though from twitter to other social sites causes chaos on Facebook's security and it does tend to cut out or crash. I'd rather just drop something in there now and then from here rather than from someone else's Facebook pages or twitter, my FB page address is here below for you to view if I have put any works on there, some of my work is on there too and other info about me as an artist.
