I would like to build a portable power supply for a 11" digital
picture frame. The 9volt supply would need to last 6 hours, Would I
be better off with 9 volt batteries tied together or use 1.5 volt
batteries tied together?

You will need to measure the current that the picture frame draws
from the 9 volt battery before an estimate can be made.
