I have a couple of opinions, but they are much the same (sort of) as others mentioned previously. Some hypotheticals, should SB go down a commercial route...
How would prices be negotiated, and who would negotiate them?
If SB were go into business selling pixelart, how would violators of copyright policy be pursued? I'm not sure how the current 'system' works.
Some drawings have several artists in the credit line.
Thank you all for your kind words. I think I can answer Jabba's questions.
• Prices: When it comes to using commercial art, "everything's negotiable," but I'll keep it simple: When I first started producing supplements, the going rate for a line drawing was $10 US. We paid that to Weyer's for a bunch of their stuff we used. But that was 1980. Given inflation, I'm willing to offer $30 US for this drawing. That's also about the price of the supplement, so it seems about right. I'm sorry if the amount is less than you might have imagined, but aside from the printer's fee, the development budget for Bywater's War is small - very small. But from your point of view, it's money you were not expecting. It's not a lot, but "a buck is a buck."
It's your decision how to split it up, but my recommendation is a 50/50 split between the artist and SB.
If Novice (or some future artist) wants more, then we can talk. We can always talk. Remember, "everything's negotiable."
I have a PayPal account, which is free to set up and is an easy way to send money internationally. It would be my first choice for sending payment.
One caution: I don't know where Novice lives, but some countries are pretty funny about foreign income. One of our regular authors, who lives in Germany, get his royalties in Clash of Arms merchandise. Why? Because in Germany, if someone receives any foreign income, they are taxed at the highest percentage possible. Not good. Getting paid in kind works for him, since he's a wargamer.
That may not be the case for Novice, but depending on where he lives, he should check his tax code. And Novice may not be a wargamer. Or there may be some other issue, but remember Rule #1: Everything's negotiable.
I also recommend that SB post whatever policy you decide on the FAQ, which is the first place I looked for guidance. Of course, there wasn't any. But new people really do read the FAQ.
• Enforcement of copyrights is up to the rights holder, and I can only speak to US law. If I see someone using my material, I'm responsible for notifying him and telling him to stop. If that doesn't work, and if he's working for a larger organization, or posting it on a website, I go to them and say, "he's using my stuff!" and they make him stop. Hopefully. If that doesn't work, then in the US you can have a lawyer draw up a "Cease and Desist" order, which is a legal notification that you've been a bad boy. If that still doesn't work, then it's time to decide if you want to sue. The tradeoff is measuring the damage you've suffered against the cost to sue.
Realistically, a nonprofit organization like Shipbucket usually wouldn't go past step number two, especially since you'd probably be crossing national boundaries.
• Artist's credits can be as long as needed to make sure that everyone is properly recognized. If there's more than one name, then the credit will have more than one name. And as I included in the example, we can have Shipbucket listed there as well.
That was a long answer, and hopefully a clear one. If not, ask away.
