I'm new in WP, and I had to make a new Content Type (news) with image. This Image is used in Post Content type also (named default_image). I'd like to place the last 3 elements from this content type to my front page with image and title (and links of course). I figured out that it's possible with Image Feed Widget (I inherited this page, and it was used earlier), but I don't know how to say my RSS Feed to use the Custom Field Image as enclosure, and how to set RSS Feed to my custom content type.
I would be grateful if You could help me.
