Adding background images and contact pictures using FRITZ!Fon

The FRITZ!Box allows you to add your own images to telephone book entries that you use often. When those parties call, the corresponding pictures are then shown on the display of your FRITZ!Fon. You can also configure your own background image for each telephone that is then displayed in standby mode. You simply use the FRITZ!Box user interface to upload the images and transmit them to your telephones.

Requirements / Restrictions

  • Only FRITZ!Fons with color displays support the use of background images and contact pictures.
  • No DECT repeaters from other manufacturers are registered with the FRITZ!Box.
  • You can add up to 256 contact pictures.
  • Contact pictures can only be added to telephone books that are directly saved in the FRITZ!Box. With online telephone books, the pictures assigned to contacts in the online telephone books are displayed.
  • The pictures must be in JPEG file format.

    Note:We recommend a resolution of at least 240x320 pixels for the images, with an ideal aspect ratio of 1:1. When you save an image as JPEG in image editing software, we recommend using "baseline" encoding (usually the default).

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
