I am not sure what you mean when you specify "an image". Is this a displayed data table window? Or is it the output from JMP Platform? Or is it an actual image display of a .jpg or .png file?

<< Get Path will give you the full file name of the data table.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
path = dt << Get Path();
Show( path );

<< Get Datatable will return the name of the data table associated with the Display Output from a JMP Platform.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
obj = dt << Distribution( Column( :Age, :Weight ) );
t = obj << Get Datatable;
Show( N Rows( t ) );

You know the name of the image if you are opening it -> get it from the filename/path. There isn't a window when you use Open() on image, it will just return the image object (at least doesn't seem to create a window in JMP17/JMP18 when run from script editor).

But you can send << Get Path to that

Names Default To Here(1);
img = Open("$SAMPLE_IMAGES/windmap.png", "png");
//Show(Get Window List() << get window title, img << Get Path);
nw = New Window(img << Get Path,
	img
);

And if you have already open windows, Get Window List() << Get Window Title works but you might not know which is your image (last opened window is the last in list).

I opened the png file with JMP by default, so I need to get the name this way.

名= Get Window List() << Get Window Title();i=1;For(i=1,i<=NItems(名),i++,aa=名[i];if(right(aa,3)=="jpg"|right(aa,3)=="png",pp=left(aa,length(aa)-4);Break()));

Using Word() or Words() can usually make getting filenames a bit easier. This will return all the window titles which end in "jpg", "jpeg" or "png"

pngs = Filter Each({windowtitle}, Get Window List() << Get Window Title,
	Ends With({"jpg", "jpeg", "png"}, Word(-1, windowtitle, "."))
);
