Issue with Image Picker running on Safari on OSX & IOS

Hi folks.
I just wanted to flag something with you about running image picker question. I made an example for students to use as a randomiser (based on Wakefield’s). It works perfectly fine on Window browsers but we’ve noticed with our Mac users that it throws up a script error prior to seeing the colour images (attached). I think Mac might have a problem with the URL that the image is saved to, but I don’t know. I’ve attached the link here too. If you have any suggestion that would be great. I can share the copy with you if you wish.

I’ve swapped out my colour image picker with a radio group question to use as a randomiser and I’m happy to say it works across Window/Mac browsers.
