For this we would need to extend the diagram-graph-xml-filter module from Diagram.DiagramSheet to add support for filtering the backgroundImage attribute of mxGraphModel. This issue is more how to do it without duplicating code.

<mxGraphModel dx="714" dy="497" grid="1" gridSize="10" guides="1" tooltips="1" connect="1" arrows="1" fold="1" page="1" pageScale="1" pageWidth="850" pageHeight="1100" background="none" backgroundImage="{&quot;src&quot;:&quot;https://eztrackit.com/wp-content/uploads/2013/07/Tree.png&quot;,&quot;width&quot;:&quot;256&quot;,&quot;height&quot;:&quot;256&quot;}" math="0" shadow="0">

The value of backgroundImage seems to be JSON.

I'm removing the critical label because setting a background image on a diagram is not a common use case IMO.
