Hold the phone folks. Looks like we've got it fixed. We are a little unhappy that the apache doc makes it unclear about return OK; versus return DECLINED;, but that aside, apparently our *not written here* ad_banners code was returning before it had done its work if it detected a file extension not on its list; it seems that positive logic like "Jump out if this is a png, a gif or a jpg" would make more sense. However, thats patched, and installed and working fine. I know grok the ways of apache in much more fullness.
