The debugger is a special mode of the interpreter that you run with the 
'-g' option.

In that mode, the interpreter read debugger commands on its standard 
input and print the result on its standard output.

Some options allows to use some fifo instead of the standard input / 
output. This is used by the IDE to debug a project.

It should be possible to implement what you want by letting the IDE ask 
the debugger to eval an expression that saves the image in a specific 
format (PNG or JPEG) inside a temporary file, and then load that file to 
display it.

Maybe it's time to revamp a little the interface of the debugger 
expression window.

You can notice that this window has already two modes for collection and 
arrays: display the object properties, or display the object contents. 
The same distinction would be added for Image and Picture.
