Thank you. That's very clear and perhaps the most important answer for everyone to know Perhaps this could be an XC5.3 suggested update?

Sometimes this happens not at the time when an image is uploaded, but at the time it is displayed in that particular width and height the first time

Again thanks for making this clear. If a re-sized image stored here, has a date over 12 months old, but the connected main image has been re-worked several times since it's original upload date, then we are assuming that this particular image (i.e. in this specific size) has never been requested by any site visitor? Otherwise it would be overwritten 'on demand' as a result of a verification check? Is that correct?

If not, then presumably the verification check used 'on demand' is only filename related and not file creation date / file creation time / file creation size related too, which would be far more effective Therefore, one more question on this matter: If ALL the images stored in /var/images are manually deleted (we mean all the images and their subdirectories too) and then "Generate resized images" located on the images page within Look and Feel is run again afterwards, it should successfully re-create them all, but they will now all be current and correct, albeit not progressive jpegs? This deletion / replacement process won't result in any X_Cart System errors either? We don't think it should, but...

Yes we do

Install ImageMagick on the server 2. Edit etc/config.php and specify your image_magick_path 3. From a custom module decorate the "execResize()" method in \XLite\Core\ImageOperator\ImageMagic class so that it calls the imagemagick binary with the extra "-interlace Plane" parameter. Does this help?

Yes this is very helpful thank you, but we think we will save the effort needed to create a new module until we switch to XC5.3 later this year as a) It may not be required (if this becomes an XC5.3 CORE inclusion ) b) It will be far easier to create a new module in XC5.3 than trying to convert an XC5.2 module (you know this better than we do!).
