If the source file for the picture you want to update is on a disk or CD-ROM, insert it into the appropriate drive on your computer.
If Publisher cannot find the original file, it displays the Link to Graphic dialog box so you can find it. Click the name of the source file, and then click Link to File.
If you don't see the file you want, switch to the drive or folder it's in.
Note If the publication has objects linked using OLE, you must update OLE links separately using the Links command (Edit menu). Be sure to update OLE links before you pack your files to take to your printing service.
