Maybe Image.FromString Picture.FromString could be used here by the
debugger to not even need a temp file and just get the data as string?

That would be amazing.

I could implement it in many ways if there was a way.
My current train of thought was to open a popup window to display the
image. another idea was a hidden panel in the expression viewer that shows
upon request for an image object.

i have been using Paint.class a bit recently to paint direct to picture
objects , being able to see the picture was a case of using Picture.Save()
in the code, i though darn it would be useful if the expression viewer
supported images. :)

Many thanks
Much respect
