CDupload.com, a popular file hosting site, is going going to shutdown. Many
blender users (including myself) have used this site for hosting images or
files, and will need to use an alternative site. Be sure to get all of your
files off that you need!
Here is the official message:
After 3 years of free hosting I regret to inform all users that this site will
shut down at the end of September of this year. So grab your files!
