Thank you so much! This worked.
One last question: would something like https://www.digitalocean.com/docs/spaces/how-to/ this work as a “server” to store my zip file with images? I don’t have my own dedicated server, so I’m looking for alternative options. Storing these images on a server of some sort would make the images/pages load faster in the experiment, right? Are there any other alternative server options for hosting images that you would recommend?
