Picture in front of node

Hello, I would like to have the picture in front of the node and not disappear.

This is what I have now :

This is that I want :

Code of the picture :
g(go.Picture, {
maxSize: new go.Size(NaN, 55),
desiredSize: new go.Size(50, NaN),
alignment: new go.Spot(0.5, 0,0,-10),
imageStretch: go.GraphObject.Uniform,
sourceCrossOrigin: () => ‘anonymous’
})

Thanks!

If you want a child element to stick out beyond the bounds of the main child element, you cannot use an “Auto” Panel. Try using a “Spot” Panel. http://gojs.net/latest/intro/panels.html
