Our client ran into trouble after messing around in the /uploads/images/Gallery
folder with the image manager and file manager. After this the Gallery module
crashed the page-generation leaving both frontend and backend pages severely
mangled.

I browsed the image and file manager classes of CMSMS and discovered that
folders beginning with a dot are hidden from the user, so I changed the first
two lines of Gallery.module.php to:

define('DEFAULT_GALLERY_PATH', "uploads/images/.Gallery/");
define('DEFAULT_GALLERYTHUMBS_PATH', "uploads/images/.GalleryThumbs/");

and changed the folder names accordingly which seems to solve our problem and
the client's confusion.

Is our client the exception or does the confusion occur more often?
