HP Photo Creations does not have a scan feature due to the fact that it was designed with a specific target: creative printing. If you need to scan your photos you can easily use the software available built in to your system: Windows Fax and Scan for Windows or Preview for Mac.
However, HP Photo Creations was designed for HP printers and if you installed the full driver from the HP Support, a scan application should also be provided along with the base driver making it easier to scan.
