Hi gennarof, to make the code more readable (just a tip), it's best to place it within [code] tags in your posts.

You said that no images/cache/ folder was created, if that's correct, then that suggests you didn't upload the files from the /upload/ folder to your site root. The /upload/ folder has the following structure:
/upload/images/cache/
/upload/include/templater/plugins/function.thumb.php
/upload/include/templater/plugins/function.thumb_imp.php
/upload/sql/phpss_dynamic_images.sql

So once you've uploaded the contents of /upload/, you should see the images/cache/ folder exist (along with the plugin files, etc). Or if you did upload properly, it's possible that your Unzip program didn't preserve the images/cache/ folder because it's empty?


Additionally, you mention that when you modified the product_thumbnail file, no images were displayed. Please check your /var/log/ directory for any PHP error log files, please post the content of the most recent log file.

Cheers
