[Radiant] Linking to an local image in Radiant

[Andrew Goodnough]

I need to add an image to a Layout.  It's in a Layout because the image will
be on every page but I also need to add images to Pages in the website.  Do
I need to install the Page Attachment extension to do this?  This
requirement seems very basic so I feel I might be missing something.

Assuming I do need this extension, I'm following the directions found here
http://wiki.radiantcms.org/Installing_Extension_-_Page_Attachments to
install it.  I'm getting an authenication error trying to get the extension.

$ svn export
