As came up in one of our current threads, internet piracy and the use of imagery is always a constant concern for those who contribute to online art communities, competitions or even your own personal websites. As we've seen on rare occasion even in this site itself, there have been those who wish to peddle others imagery as their own.
So here's a thread to voice some of your suggestions, as a community, as to what you think are good ways of protecting your imagery.
In rush at the moment so I'm just going to paste my previous post here. : )
---------------------------------
honestly, I don't think watermarking is really necessary. not in the
large scale as a lot of people do and it really detracts from the
image.
one thing we've consitently tried to get people to do on
this site is to keep your images small. create them at high res but
save a version that is 700 px wide or less and make sure the image is
under 500 kb in size, preferably less than 300 if you can. smaller the
better.
reason being, images that are this small are no good
to anyone when enlarged to a printable scale. the best anyone could do
with them without them getting pixelated or blurred is to use them
online or in small ads.
you can never really stop the piracy
without either destroying your work with large watermarks, or you just
don't contribute. neither are really going to benefit you much. so if
you keep your images as small as possibly with them looking good, then
that's really the best you can do.
