kaa - I have installed library and run the "Hello World" program successfully. I am having problems with the other tutorial which I think may be related to a bad registry. I am installing Windows 8 tonight, which should fix the problem. CImg works ok with Win 8 and Visual Studio 2012. I mean, it's just a library, right, so should be no problem?
oh wait. I just thought when I saw your original post in my reply - I haven't installed ImageMagick which I think is necessary for that tutorial. Anyway - my original question still stands please.
