It's flattering to have a photo selected for editorial use ... I just prefer a proper credit (though SOME credit is better than none).
Example: Gizmodo, a Web site full of leaks and breaking news for techies (I prefer their competition, Engadget) in August did a piece about a spate of upcoming technology products coming from Verizon (headline: "Verizon Readying a 15 Phone Barrage for the Rest of '07").
They cleverly overlaid the Verizon logo on the barrel of one of the guns at Fort Casey -- an image I shot about the same time.
My gripe is the lousy credit: "Image via Flickr."
Flickr? I took the freakin' picture. Image by Paul Swortz via Flickr.
At least they point back to my original and provided SOME credit, which is more than many do today ...
