Errors

Hello and thanks for the report. Are you running the calendar customizer locally or on the CodePen demo? I know crossorigin.me has given some issues in the past, but I'm not getting any errors like you're showing on the CodePen when I try to run it.
@ZachSaucier i run Cc on the Codepen
Could you try refreshing now and see if it still gives errors? I made a couple small changes to the cross origin part.

After i press Invert colors

After i check Round image values

The other errors after the first are all due to the first one (the image not properly being loaded) so they can be ignored. Can you try viewing the image source: https://i.imgur.com/z2qG0gs.jpg and tell me if you're able to view it or if it's forbidden?

I was redirected
Interesting. So that's the problem then. I tried publishing the image to community to see if that can help. Can you try visiting the direct image URL again to see if it redirects you still?
I was redirected only after F5 on page with image. Before reloading page I see image
Problem solved now.
Maybe bundle all resources and publish to github-pages?
I should do that. I'll get to it when I have some time.
