Hello,

I am new here and wanted to ask a question about copyrighting digital drawings. It has no direct link with Inkscape as such, but it's an issue that I imagine lots of you are familiar with, and I'm not.

I recently began making drawings in inkscape (great program by the way) instead of on paper, and now a musician friend would like to use one of my drawings as an image for his album or song. As I am fairly new to digital drawing, I ask myself how I go about copyrights and incomes generated?

I have my drawings deposited via on online service so I can prove, if necessary, that the original SVG was created by me on such and such date. This service gives me a confirmation that file X with MD5-sum Y has been sent to it on date XXX. So that's covered, in case of trials and such. (Right?)

But I still have the following questions:
1) If I want to grant my friend non-commercial use without being paid for it, just him mentioning my name and website, how do I go about that? Do I make a contract he should sign, and what does it state? Or do I just send him a bitmap (not the original SVG of course) along with a CreativeCommons copyright notice? Or ...?
2) I would like to have an agreement where I would receive a percentage of possible sales of his album. So he doesn't pay me anything to begin with, but for every ten dollars he makes he owes me one, for instance. So if he gets rich and famous one day, so do I Is that practically and legally possible? Does anyone have any experience with this?

I am a Belgian citizen by the way (currently abroad in Spain), if that matters.
Any ideas or links would be greatly appreciated, many thanks in advance...
