How do add text to a cell that has an image loaded?

Is it possible to add text to a cell that has already loaded images?

dt = Open( "$SAMPLE_DATA/Big Class Families.jmp" );
For( iRow = 1, iRow <= N Rows( dt ), irow += 1, 
// open the original
	original = dt:picture[iRow];
	{xSize, ySize} = original << size;
// use a frame to do the drawing, make the original fit the frame exactly
	gb = Graph Box(
		<<backgroundcolor( "orange" ), // to see errors better
		FrameSize( xSize + 1, ySize + 1 ), // the +1 is required, 4 times
		X Scale( 0, xSize + 1 ),
		Y Scale( 0, ySize + 1 ), 
	// apparently x and y are different. this is correct in 17EA.
		<<Add Image( image( original ), bounds( top( 0 ), Left( 1 ), bottom( ySize ), Right( xSize + 1 ) ) ), 
	// draw something on top of the image
		Text( Center Justified, {xSize / 2, 10}, dt:name[irow] );
	);
// capture an updated image
	updated = gb[framebox( 1 )] << getpicture;
// crop added border. "updated" is the final image.
	updated << crop( Left( 1 ), top( 1 ), Right( xSize + 1 ), bottom( ySize + 1 ) );
	dt:picture[irow]=updated;
);

...and the orange background is because those images have transparent pixels. Your images probably don't have transparent pixels, so you probably won't see that. Preserving the transparency while adding text is a lot harder.
