In Odoo14, in the beginning all images added to the website where available to be used again if needed in the wizard. But it stopped showing new ones at some point. So we have to upload them again each time... 

Strangely, some images still make it to the wizard but seems to be page related...

In postgres, it can see images and their store_fname which also confirm that we now have many duplicates.

I would like be able to select already uploaded images and also to clean all duplicates.q
