I totally agree with his post. Here are some examples of mine:
- Eurostar: wanted it for nothing, didn't even reply when I enquired what they would pay
- Watford Museum: as this is non-profit, and I live in Watford, I agreed. This led to work from Watford Council. Watford Museum were absolutely brilliant to deal with.
- Construct Ireland: didn't offer to pay but when I brought the subject up, agreed to it without a problem.
- Numerous wildlife charities and research organisations: These all get them for nothing.
I urge you - even if you're agreeing to give it away - to make clear the terms of your license. If they have asked for it for a leaflet, make it clear that you are granting a license just for that one usage.
