What is even more frustrating is seeing people who DL images from the net that obviously belong to others...especially photographs....toss them into a paint program and frell them a bit, slap their name on them and take credit for having been the creator. Some actually have gone to the extent of posting on the web page the images appear that they are for sale! Go figure.
I saw one such at Renderotica that had obviously grinched David Hamilton photos...I have all his books since way past when so I know whose they were...and did the same thing and collecting kudos and applaus from the others there seeing the work.
I had to say something knowing at the same time noone was gong to bother doing anything about it. See a lot of that over at DeviantArt too.
That is the failure and curse of the internet...where everything belongs to everyone and everyone knows your personal S#!+. Scarry!  :(
