The editor of a magazine whose combined print and digital subscribers number roughly 1.5 million approached me asking to use one or two of my photos in one of their articles. They offered $100 USD per photo, so not a ton of money, but it's not like anyone else is clamoring to get these photos, so I agree, on the condition that the photo is attributed to my website url, (which is just my name with ".com" on the end) so at least maybe there's a chance I'll get a couple hits out of the deal.
The editors response was "We don't print websites as credits."
That flat refusal kind of left a bad taste in my mouth, because I don't see why the magazine should care how the credit reads. That and the relatively low sum of money at play makes me inclined to just walk away.
But then again, I don't want to be a jerk - could there be a legitimate rationale behind their refusal that I'm just failing to appreciate?
