Auto Backdrop will quickly create a backdrop from the selected photo.
Note that the size of the created plane will be equal to the image resolution. The script will automatically add UVW and Bend modifiers to it to make it curved. You can hold shift to create a plane without segments and modifiers. The default intensity of the backdrop is 5, with the Emit Light = on option.
To use it, click on the button, select a photo, click OK, and then pick a point to place backdrop.
