There is a problem with your environment because the Application Express files have not been loaded. Please verify that you have copied the images directory to your application server as instructed in the Installation Guide. In addition, please verify that your image prefix path is correct. Your current path is <Images Folder> (it should contain both starting and ending forward slashes, such as the default /i/). Use the SQL script reset_image_prefix.sql if you need to change it.

Solution:

Use rest_image_prefix.sql script to reset the images folder.

edit ords.properties file and fix the imags folder path.
