Seen in a post on www.microstockgroup.com. I think it says it very well )
I get a lot of requests to use my photos in miscellanous projects. Of course it’s flattering and it happens that I accept. On the other hand – my photos aren’t that expensive. A lot of them can be bought for a few bucks, so it won’t ruin anyone to pay me my humble fee. Especially when they are going to use it as cover art or along with an article in a magazine. So please – photographers can’t eat credits. If you pay us with credits, we’ll just start eating eachother and you’ll have fewer photos to select from in the future.
