var pictureMarkerSymbol = new PictureMarkerSymbol('../images/GoogleMaps/' + jsonObj[0].Table.Color + 'Diamond.png', 20, 20);
graphic = new Graphic({
geometry: point, // Add the geometry created in step 4
symbol: pictureMarkerSymbol, // Add the symbol created in step 5
popupTemplate :popupTemplate
});
view.graphics.add(graphic);

You can understand the issue from image showing popup but no picture marker symbol showing but my machine it showing and other any machine it not showing

It should Display like this on other machine.
