Cytat:Publishing the unlicensed, watermarked, sample or comp version of an image.

iStockphoto provides free, watermarked comp images to use in mock-ups or layouts. An iStockphoto comp does not include any licensing so if you publish a watermarked file, you do not have the rights to use it. It's also embarrassing to publish an unlicensed image with a big, blatant watermark all over it. Don't forget to swap the comp for a paid-for licensed image so your final product will look the way you intended it to.
