I published this file as author under the Creative Commons License CC-by-SA-3.0.. This means that a ‘free use outside Wikimedia’s projects’ is only possible under the following conditions:
It is not sufficient to just mention my name. This is necessary in any case. Naming the author does not release from the obligation to properly license the photo. Also, a link to Wikipedia or Commons is not sufficient and counts as license violation.
If a mention in this form is not possible, please contact me before a planned use.

A license notice by hovering over the file is not sufficient, as this is not displayed e.g. during mobile access. The license notice must always be visible.
