How do I upload photos into my assets list/library? I get the following error message when I try to upload the photo:

"Upload failed. The error message was: Error uploading the file: The file system path "/home/tramweb/public_html/craft/assets/content/" set for this source does not exist."
Have you created that directory? If not, you need to. Also be sure the directory you create has the correct permissionss (writable by the web server)
