When having your film developed, you could ask to have the photographs put on to a CD or DVD. This costs only a couple of euro.
I'm not really sure exactly how digital photo frames operate but I presume it would then be possible to load the photos on the CD to your computer and then on to the digital photo frame memory.
It is also possible to scan negatives via a photo scanner and save to your computer, and again presumably on to the DPF memory device.
Not sure if this is of any help to you.
