JSON output format doesn't use "I" drawing command

I’m trying to generate JSON from the dot graph:

digraph G {
  a1 [image="image.png"];
}

However, when I run

dot.exe -Tjson input.dot -o output.json

I get the following warning

Warning: No loadimage plugin for "png:json"

The resulting output.json doesn’t use I draw command from here xdot drawing commands

Is it possible to generate a JSON file that contains the draw image command?
