All pictures published on this website (except the profile picture on the main page, design elements and pictures used as background headers and the site logo) are, if no other information is mentioned on the respective page or the respective contribution and it is not a quotation or other, marked, foreign work (for example when noted as square brackets in the caption of the picture, e.g. [4]), published under

CC BY-SA 3.0 DE

You are therefore free to reproduce, redistribute, edit, modify and use the pictures for any purposes, including commercial ones.

Under the following conditions:

A proper attribution must be provided. This can, for example, take the form of a scientific citation (e.g. in the caption with [2] or a comparable and corresponding reference at the end of the page) or directly below the graphic. The mention of the name does not have to be an advertisement that can be read from a long distance, but the origin of the graphic must be comprehensibly marked for interested parties. A font size of 7-10pt is sufficient for this. The licence CC BY-SA 3.0 DE must also be referred to in a suitable place. The text may read as follows: “Image: Hartrusion.com, CC BY-SA 3.0 DE“. It is not suitable to provide attribution on separate pages.

Sharing under the same conditions: If content or images are used or processed in any form, the work may only be further distributed under the same licence.
