) on the bottom of that page. You should read it all, but here are some important excerpts:
|> You can use my artworks on your website (blog) if this site is personal, not business or organization:
|> - clickable link to vladstudio.com is required on each page where my art is used;
I don't think we can make clickable links in map descriptions and just playing a game also counts as "using my art", so every game would need a link as well...
|> Without my explicit written permission, you cannot:
|> - use my artworks in graphics for your business (illustrations, game backgrounds, etc);
|> - use my artworks on website that brings you profit (such as business site, auction, etc) or represent your organization (even not-for-profit).
A WL map would probably count as a "game background". Whether or not WL makes a profit at the moment, it would be highly impractical to have a map which can only be used so long as WL doesn't make a profit. No idea whether WL counts as an organisation (if it does, the site surely "represents" the organisation; it's its only form of existence).
|> You absolutely cannot:
|> - use my artworks in any way without giving credit (linking) to vladstudio
|> - use my artworks in HTML templates (such as Wordpress themes, etc), Flash templates or other redistributable web products (free or paid).
If a text-only (non-clickable) link is good enough, that could work, but I'm still cautious. The last one is also a big problem; I have no idea whether WL counts as a "redistributable web product".
And, most importantly, what you already said:
|> To get such permission, contact me and describe where and how you'd like to use my artworks.
If you want to do this, [get in contact with the guy](http://www.vladstudio.com/contact/
