All photos you upload to kaufmich.com will be watermarked automatically after you have activated them. Should this not happen for technical reasons, you can always add the watermark by hand. That way, the original source kaufmich.com is "stamped" on your picture and your picture is better protected against unauthorised copying.
You can choose transparency, position and colour for the watermark so that your image quality does not suffer. To do this, go to photo gallery in your settings and select one of your photos, move your mouse to the top right of the image, click on the three dots and then click on the "Edit watermark" menu.
After you have made the desired settings for the watermark, select the button "Save and view" and only then the watermark will be placed on your image - done! You can then close the window!
