I think crediting everyone can too easily result in a list so long as to become ludicrous so I almost never do. As for commercial items I think the vendor is much more interested in my money than a credit line. By giving them my money I have given the highest compliment necessary. As for free stuff, well what compliment could be higher than actually using it? None the less, I realize that many do not feel this way so I almost never use anything but commercial models or those I have created myself. As a side note, in the past I have given away a few models. My "license" was extremely explicit in stating you could do anything you wanted with it, even sell it. It also specifically stated that no credit was necessary or expected. What I have done on some of my sites is to inlcude a "blanket" page specifically itemizing the software products or model vendors I have used. I included a "thank you" line for those who offered their goods for free. - Jack Valero
