+This tag, when present, allows for specifying many different images sizes in a compact way.  The syntax is borrowed from the HTML5 [srcset](https://html.spec.whatwg.org/multipage/images.html#srcset-attributes)
+syntax.  It allows for describing multiple image sources with width and pixel hints directly in the attribute.

+Example of a single gateway:
+```xml
+<podcast:images

+            https://example.com/images/ep1/pci_avatar-middle.jpg 600w,
