General questions for the QualiTeam chaps...
Images. We use jpeg images and as part of reducing various various page loading times (mainly static pages) we have just converted every single one of our own site images (!) from jpeg baseline to jpeg progressive and re-loaded them all
Questions are:
When using "Generate resized images" located on the images page within Look and Feel, are the generated images provided in exactly the same format as the 'new' originals? i.e. progressive not baseline jpegs in this case? Plus, where are they stored once created? It's not in the same area as all the main images or in /var/images below as far as we can see....
Images stored in all the sub-directories below here: /var/images; what is their purpose? They date back to when their respective main images were first uploaded (a long time ago....) Re-deploying the store does nothing to them it appears, hence what purpose do they serve? If main images are changed / amended / updated etc how are the images stored in /var/images and subdirectories of same dealt with? Thanks!
