Deborah,
   The full-resolution images, in processed image form, are NOT available anywhere from the web page you cited, only the lower resolution images and raw data for creating the full resolution images, which I don't have the expertise to do. The only place where I have seen the full resolution (24k x 24k) processed images are on the ESASky site, so clearly you have them!  But you still have not explained WHY you cannot make them available for download. 

Please escalate my question to somebody higher up, if necessary, who can provide a definitive answer as to why ESASky cannot make the full resolution images available, or otherwise provide links to where they can be found, if at all.  Thank you.
