you save the graphics into the Alpha/Icons folder.  then you need to add each graphic as a device.  then you can cut and paste the graphic from your main page, over to another device page.  it will ask if you want to delete the device when you cut, choose yes.

keep in mind that if you email the file to someone else to load onto thir remote, they will have to have the same graphics stored on their computer.  the remote file doesn't actually store the graphics, it just tells CCP where to look for graphics when downloading to the remote.
