Magazine cover compensation

[dutch]

I've got someone from a magazine wanting to use an image from this set as their cover image for a new magazine:

Head - a set on Flickr

I wondering how much to charge. This new magazine will be going to advertising agencies around the world and should be fairly high profile. The company is based out of Montreal.

I have no experience with this kind of stuff, so i thought I'd ask you guys. Also, as a side note, should I insist on sending the images only after payment is received, but send watermarked versions to prove they do exist?

Thanks,

Eric

Good idea, watermark the whole image before sending it off to them.

Do you know where in the magazine you'll be printed? Front page, inside half page, just a 4x6?

To make yourself look professional have a pdf ready to hand in with all the different sizes with a prices in mind
