I price things sorta differently, mainly session fee wise. Yes, they are using the photos as advertising, but, I will get a heck of a lot more for the cover of a magazine like KV vet than I will for the photo I sold for the cover of Dog News.

I get a lot less covers of *commercial* magazines though. I make more money off of portraits, as they are more emotionally based vs need based. You buy more from wants than you do needs.

If I put it on the web, I know it will probably be lifted. If I put it on my web gallery site, it is heavily watermarked with "Image not purchased" and my name in a opaque bar.
