locally hosted image ads not displaying

Placing a remote ad snippet using channels results in no ads being served, despite ads being saved in both relevant channels and no channels (with 'Always' selected for channel display settings).

Looking at the ad serving script debugging info, it appears to my untutored eye (my js sucks) that the system is pulling up an ad, but the system is failing to write the image to the page. But judge for yourself:
