Hello Sébastien,

XEP honors 'Expires' field in HTTP response headers and makes use of
'get if modified since' request. All you need to do to prevent XEP from
retrieving each image three times is to configure your web server

If an Expires field is set (to a reasonable value), XEP will get an
image just once. Otherwise, if the image was not modified on the server,
XEP will get it once and check it was not modified twice (200 304 304).

Best regards,
  Michael Sulyaev,
