If you are looking to use one or more of my images commercially, please contact me via e-mail (morjer [at] googlemail.com), so we can work out an agreement. I usually reply to e-mails within no more than two or three days. Examples of commercial use include: Company web pages, apps, product labels, book and magazine covers and merchandise.
License fees vary depending on the use.
SOCIAL MEDIA - PERSONAL
If you wish to post or share my images on blogs, web pages and social media accounts (e.g. facebook, twitter, pinterest or tumblr), you can do so without prior permission, but all images must be accompanied by a link back to my site (www.morjers-art.de) or DeviantArt account (http://jerry8448.deviantart.com).
Thank you! :-)
SOCIAL MEDIA - COMMERCIAL
Use of my images in social media by commercial entities is the same as "commercial use" above.
Classroom use by students and teachers as part of reports, presentations, worksheets, etc is free and does not require prior permission as long as the use does not involve uploading the images to the internet.
DERIVATIVE WORK (for example photomanipulations)
Please DO NOT use my images for your own digital artworks. It takes me hours over hours to create original pictures from scratch and I try to encourage everyone to do the same.
