This function creates thumbnails from images. The function saves the new thumbnail images in a thumbnails subdirectory inside the original directory. The system prepends thumbnail filenames with tn_ (for example, tn_picture.jpg).
Important:
When you disable the WebServer role, the system disables this function.
