The license for the main version 6 is in effect for all updates to this version. Improvements or new features for Foto-Mosaik-Edda will be published as updates with the new side versions (i.e. 6.6 or 6.7 or 6.8 …). The purchased license is also in effect for these updates.
A new main version 7 or higher is not planned, at the moment.


No, Foto-Mosaik-Edda automatically resizes the photos and puts them in the database. The original photos will not be altered. After the photos are added to the database, Foto-Mosaik-Edda does not need the originals anymore.

Foto-Mosaik-Edda evaluates the EXIF data of the photos while they are being added to the database. If the EXIF data shows that the picture was taken with a camera in portrait format, then Foto-Mosaik-Edda turns the photo before the addition to the database.

If the photo was manually turned (in a program which ignores the EXIF data and does not correct the turned photo) it is possible that the photo is properly turned, but in the EXIF data it will still be marked as needing to be turned. In this case, you have two possibilities:

  1. Edit the photos with a graphics program in which the EXIF data is correctly interpreted and corrected
  2. Configure Foto-Mosaic-Edda to ignore that EXIF data. Follow these instructions (for versions 6.6x and higher):
    • End Foto-Mosaic-Edda and open the file " C:\Users\<USER>\Documents\Foto-Mosaik-Edda\settings.config " with an editor.
    • Edit the row " <IgnoreExifData>false</IgnoreExifData>" and change it in: " <IgnoreExifData>true</IgnoreExifData>"
    • Save the file. Foto-Mosaic-Edda will now ignore that EXIF data during the addition of the photos to the database.

Program Error

Foto-Mosaik-Edda could not process the photo mosaic picture all at one time because the picture size (number of pixels) was too large for your computer/ operating system, and it needed too much memory. The size of the photo mosaic picture in pixels is a result of the definition in PPI and the printing size. Please reduce the size and the definition if possible, and then it should work. For a poster, a definition of 150 PPI is more than sufficient. On my modern PC with Windows 7 64bit up to 500 MegaPixel is possible, depending on configuration.

If you would like to creat a photo mosaic picture with a very high definition, you have the possibility to automatically divide the picture into multiple parts. Foto-Mosaik-Edda divides your photo mosaic picture to save memory, and it processes the individual parts one after the other. Each part results from separate graphic data which you can, for example, put back together into a gigapixel mosaic in photoshop later.

For more information about the terms definition and size, see the article Definition, DPI and PPI .

The .NET Framework 2.0 is probably not installed. Install the .NET Framework on your PC: Download 32bit, Download 64bit .

The font " MS Reference Sans Serif " is damaged on your system or not properly installed. If your operating system is "Microsoft Windows Vista" it can happen that during the basic installation of the operating system the font was not properly installed. If this is the case, you have to re-install the font on the menu Control Panel/ Fonts to fix the problem.
