When Importing an image for BYON it would be great to be able to preview what the notebook will look like in the Jupyter Launcher page.

The preview could appear at the top or bottom of the modal and refresh as the user inputs data.

This would help users to see how the fields they are inputting impact what the user will see when they are completing the form.
