Upgrading PrestaShop v.18.104.22.168 over to v1.5+ or v1.6+ results in missing images for categories & products. Steps taken to resolve PrestaShop images missing after upgrade.
I have performed the following steps to display some of PS missing product images.
Step 1.) Confirm that your images do indeed exist on the server.
Step 2.) Edit the /config/settings.inc.php creation date to something early such as 2010-09-05
Step 3.) BO preferences > image = move images and regenerate thumbnails for all products.
Some of the missing products in my situation where contributed to PureFTPd LimitRecursion being set to 10000.. How to edit Pure-FTPd.conf file.
Images are stored in the /img/ directory of your PS root installation.. Product images, are located in following sub-directories /img/p/ & Category images /img/c/
Images uploaded will apply a number value for labels (e.g. 1.jpg) and re-size to values, such as; 1-home.jpg | 1-large.jpg | 1-medium.jpg | 1-small.jpg
PS v.22.214.171.124 uses image label as: /1030-1340-home/
PS v.1.5+ uses image label as: /1340-home_default/
