I was using it to fetch featured image from a feed I didn't own, which means I couldn't change the output and the feed wasn't getting the featured images (so I couldn't use get_featured_image). So I ended up with this solution where I took the first image of each post instead and used that as my featured image.
Is there easier ways of doing this?
