Or just use a free online RSS Feed preview tool (as seen below).And of course you can also test by adding to a RSS feed reader like Feedly.
While some people may think RSS feeds are dead, they are still used by a lot of different services. I can easily read Feedly on my phone while I am on the go. So if you someone subscribes to your blog via Feedly, you definitely want your featured images to show up.Well, with this plugin, you can let people subscribe to each of these categories separately. You’ll see a list of the categories that you can create a feed for.As you can see, I also used the section for custom categories and pointed them to external sources, which is the trick I mentioned above.After installing it, you don’t need to do anything but to go to the page or post where you want to add a certain feed, and then click the FEEDZY icon: Once you do that, a window pops up and presents you with all the available options.Just fill in the information, set the customizations and you’re almost done.

You can also post your RSS feeds as widgets – by going to and dragging the “RSS” widget to any widget area.
