According to the IANA (at, the correct MIME media type for .psd Photoshop files is "image/vnd.adobe.photoshop". Use whatever works for your particular server and clients' browsers, though.

Are there any freeware programs that can open psd files?

There is an Open-Source that I use called GIMP (GNU Image Manipulation Program) I believe is what that acronym is. I use it for all my graphics.

They have a Mac & PC version. I have worked extensively with both of them.
