Thank you so much Mimiste! I was just looking at those "crossOrigin" snippets in "c2runtime.js" when I happened to log back into this forum site. Scorm Cloud looked into the issue and said that whatever was loading the images, which we know is "c2runtime.js", was not accepting/using their authentication cookie. I guess the "crossOrigin" property that was being set on the loading objects as "anonymous" must, in some way, ignore or overwrite the accepting of the cookie from Scorm Cloud and like sites.
Thanks again!
