Once you have successfully uploaded a picture, the accessory selection screen will be displayed.
This time choose “Photo Frame (16×9)”. It is an accessory for displaying images with a 16:9 ratio.
The picture should now be displayed in the scene. Just like with 3D model assets, you can both rotate and scale the image. Besides the 16:9 resolution frame selected this time, there are also square frames, accessories for images covering the entire sky, etc.
