Images in MIT app inventor

I want to display the image of the product after it’s being identified by barcode scanner.
How can I program the image part, what blocks do I need ?

I would make the name of the image to match the barcode number of the product:
Example: 811196011165.jpg will be the picture of an Ultra Duster can.
When the scanner returns the code, you only have to join a “.jpg” behind it and presto! You open that image.
