Thanks for that Live link.
When I view the browser console and see where those files are coming from, it looks like they are being referenced from CSS files:
Local’s Live Links aren’t able to rewrite the URLs within those CSS files, so in order to have the images show up over a Live Link, you’ll need to prevent the page builder from writing those styles to a file.
I’ve never used Oxygen, but I was able to spin up a demo site and found that there’s a setting to “Enable CSS Caching.” You’ll want to disable this setting so that the Oxygen plugin is writing those styles into the page source. Here’s a screenshot to help visualize:
Can you try un-checking that setting and re-sharing the Live Link to see if that works?
