@ammartist Thanks a lot for your report!
Have you tried clearing the cache and hard-refreshing the browser? Does it work in other browsers?
Could you perhaps open your browsers developer tools (press F12 on the keyboard) and check the "Console" tab for any errors? If you go to the "Network" tab, are there any failed requests for images? It should look a bit like this:

Finally, do you see an image when opening https://google.github.io/web-stories-wp/static/beta/images/templates/beauty/beauty_page1_bg-alt.png directly in your browser?
Hi Swissspidy,

Thanks a lot @ammartist! It looks like the issue is caused by Adblock Plus, which wrongly blocks requests for the images in templates. I recommend disabling the ad blocker on your site so that no images will be blocked.

Now the question will be how to prevent Malwarebytes from blocking them and whitelisting it
I can confirm that it's indeed the Malwarebytes Chrome extension causing this!
It looks like you can whitelist the domain as follows:

This did the trick for me.
Note: once we release the stable version of the plugin, the domain will be different from the one in the screenshot, so it might be the case that you'd need to do this again once we release the stable version.
Yep, that work's perfectly now ;-)
