Video is incorrect relative to the Exercise Environment
There is a discrepancy in the video for the 'Introduction to Pega Marketing (7.13) course' If you go 1 minute into it, you'll see it asks for the value of 'webwb/iPhone6s.jpeg' in the campaign image field. That image does not exist in the exercise system.
If you look in the exercise system, you'll see that it doesn't exist. Can you fix the exercise system so it matches the tutorial video?
