Works drawn by our own generator come to you under the terms below. Take one, use it, change it, sell what you make with it. Two things only are off limits, and both are about the collection rather than the picture. Works from open collections are not ours to license at all — those are free of us entirely.

You can

• Download and use the files free of charge, for personal and commercial purposes alike.
• Set them as wallpaper, put them in a design, ship them inside something you sell.
• Crop, recolour and modify them however you like.
• Do all of the above without asking us and without crediting us.

You cannot

• Republish the collection. Gathering Tessarum works into a gallery, an app or a stock library that does what this site does is not permitted, whether free or paid.
• Sell a file unchanged. Selling a work as it stands — as a download, a print, or on an object whose value is the picture itself — is not permitted. Modify it meaningfully and what you made is yours to sell.

What this covers

Works drawn by Tessarum. They are generated by a program we wrote, from palettes and settings we chose, and the rights in them are ours to give away on these terms. Images sent in by visitors are not ours and we license nothing on their behalf; none are published at present.

Works from open collections

The collection also holds engravings, drawings and paintings that are out of copyright, or whose holder has released the photograph of them under CC0. Those carry no terms from us. You may do anything with them that you could do with the original file, and nothing on this page restricts you.

We claim nothing over them by having framed them. Choosing a crop and resizing it is a mechanical act and creates no new work, so the file you download is the holder's, not ours. Each such work names its author, its source collection and the page it came from, so the claim can be checked rather than taken on trust.

Age alone is not what makes them free. An engraving from 1705 is out of copyright, but a photograph of that engraving can be a new work with a living owner — which is why the collection takes only files whose holder has said otherwise in as many words.

The ordinary small print

The files are provided as they are, with no warranty of any kind. We may set different terms for works published later; doing so takes nothing away from what you have already downloaded, which stays under the terms it carried at the time.
