No images showing in admin product preview page

I am in the process of upgrading from version 1.3.9h to version 1.5.1. We are currently in the final testing phase before going live. We have one minor problem we just can't fix. In the admin module, when displaying our current products, adding new products, or copying products, the product images do not show in the image slot on the right side of the preview page. However, if you go to the catalog and look at the products, the images appear there with no problem, including new images that have been added. I have looked for threads on this issue, but I just can't find any. Please if you can help.

Sounds like the URLs and paths in your admin configure.php file are incorrect.

Thank you. I had a typo on my admin config file.

In case this happens to anyone else, you need to find
define('DIR_WS_CATALOG', '/');
andrew put in your shop directory name with the trailing slash. eg
define('DIR_WS_CATALOG', '/store/');
