Product and category images are not visible in the storefront

Once uploaded to the server, product and category images may not be visible in the storefront of WebAsyst Shop-Script. There are several possible causes of that problem:

1. Image file names contain illegal characters, e.g. extended characters of Latin-based or non-Latin alphabets, or whitespaces. Rename the files using only basic Latin characters, hyphens and underscores and re-upload them to the server.
2. Permissions of image files do not allow the web server to read their contents and display in a browser. Assign wider read permissions to all files in directory /published/publicdata/DATABASE_KEY/attachments/SC/products_pictures to make them readable by the web server.
