If images aren't showing in your RSS feed, Hotlinking Protection is probably causing this and can be turned off. You can do so by going to your Scrapeshield app:
Alternatives to turning Hotlink Protection off:
1. Add the feed subdomain to your Cloudflare DNS settings as something we don't proxy. If you're using Feedburner as an example, the CNAME entry would look like this:
CNAME feeds is an alias of feeds.feedburner.com
You would then make sure the cloud is toggled to gray in your Cloudflare DNS settings.
2. Create a hotlink ok directory on your server.
3. Use a Page Rule to exclude the URL from Cloudflare.
