   I found that images that show have a mesage in the debug "<!--Cache-control: 
no-transform, preventing rewriting of ...." and images that don´t show have a 
debug mesage like "<!--Resource headers are preventing rewriting of...."
   So a thing to check is the origin headers. I can´t check cause i get a 
intermitent forbbiden mesage when a try to fecht a image from 
https://doctrans-tw.eletang.com.tw, maybe the origin server is returning 
intermitent 403?
   Anyway, after a bunch of page refresh I get all images with 200, and 
rewrited by pagesped but in the next hit gave 404 again.

   With a original image I get a 200
