Graphviz in Lyx and relative paths

[Robin Rosenberg]

Hi,

Can I use custom shapes in graphviz with Lyx and have
relative paths somehow?

Working graphviz file:
digraph {
        testare[image=</my/dir/UMLActor.png>]

}

I'd like to use this file instead, so I can relocate
the Lyx document directory.

digraph {

        testare[image=<UMLActor.png>]

}
