I was suggesting something simpler.  Something along the lines of:

======================================================
--- filters/coral_cdn_filter.py
+++ filters/coral_cdn_filter.py
@@ -14,4 +14,10 @@
              component[1] += '.nyud.net:8080'
              node.setAttribute('src', urlparse.urlunparse(component))

+            try:
+                import urllib
+                urllib.urlopen(node.getAttribute('src')).read()
+            except:
+                pass
+
  print entry.toxml('utf-8')
======================================================

The idea is to force the CDN network to preload the image.  Yes, 
sometimes it fails, and I can't explain that.  But when it succeeds, the 
image should be ready for you the first time you (the human) load the 
output page.
