  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.

  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.

  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.

I would be very grateful if you could send me a specimen copy of the photo/map or the details of the website where the photo/map will be used. Basically, all my photos and maps can be licensed under the conditions of the Mittelstandsgemeinschaft Foto-Marketing (MFM).

Please send an email to lizenz AT arne-mueseler.de if you

• need the photo or map in a higher resolution,
• require my address for sending a specimen copy,
• want to use the photo or map for a fee, i.e. not under the license specified,
• have further questions on license-compliant use.
