 * Hi,
 * So I’ve been noticing recently usage spikes in New Relic that pointed to the 
   curl_multi_exec function. After finding out that it was used by the AMP plugin,
   I then also noticed that the curl_multi_exec function was busting my site’s cache
   and being run on every page load. I then went ahead and modified the AMP plugin’s
   code to use fast_image instead of faster_image, and the usage spikes & cache 
   busting completely stopped.
 * So I’m not sure what’s going on with the fasterimage function or how it is able
   to get through the cache on every page load, but it is surely causing issues 
   with my site.

 * Would there be a way, through my theme’s functions.php, to tell the plugin to
   use the fastimage function (which doesn’t use curl_multi_exec) instead of fasterimage,
   at least until the issue is investigated?
 * Thank you.
