Pricing For International Sales As Wall Mural

Komar is a German company that is long-established and sells wall murals in sizes like 8" to 12" and average prices in the $80 to $120 range. The product is like wallpaper of an image. They sell internationally and you can see their offerings in the USA on Amazon. I've been primarily selling images with Royalty Free license through Getty Images. They charge $50 to $575, typically, averaging around $200 and they pay me 20%. The buyers have tended to be advertising agencies, web publishers and just a few small distribution magazine publishers. They've done Royalty style license on just two images that were licensed to re-sellers.

I'm thinking that this type of sale should be under a Royalty agreement. If not, the the RF license should be a lot more than $500, but I can't figure what's fair.

Has anyone sold under this type of arrangement? If so, what type of license did you offer and what range of pricing?

I'll start focusing on using my high resolution camera more and using the tripod for the most innocuous shots. (I would have never dreamed that the shot would sell).
