Via dialogue “Image” all graphics being loaded into the EIBPORT can be selected. Dialogue “Graphic Transfer” serves for uploading graphics into the device. The dialogue can be called via “Extras” > “Image transfer”, or alternatively using the arrows beside the drop down menu “Image”. Graphic files also can be drawn by drag and drop directly onto the visualization surface and are also available in the dropdown list.

If the Image’s size was changed this button resizes it to the original gauge.

defines the time period for the automatic refresh of the webpage
Entering a “0” means “no refresh”

Realizing cover display in visualisation
By the external function call screen, there is the possibility that actual cover picture to the Squeezebox ™ Server played piece of music show. If the image exists, the server can be found at the following picture is available:
http://<server>:<port>/music/current/cover.jpg?player=<playerid>
This URL is extracted from http-Api of SqueezeCenter™ resp. SqueezeboxServer™ software. For a player ID, the assigned name of Squeezebox™ will be used. Assume SqueezeCenter™ resp. SqueezeboxServer™ software works on a server with the ip-address 192.168.1.10 on port 9002 and it is about a cover image of a song, which is just played on Squeezebox™ Boom (named sqbboom), the URL will be:
http://192.168.1.10:9002/music/current/cover.jpg?player=sqbboom
By adjustment of the picture element, it is to consider, that the picture could be refreshed indeed, but it will not have to reflect cover of the actual song, because displaying cover is not connected directly with music control. In case of that a music album doesn`t contain any information of cover, server software displays a wildcard.
