I have printed only 50 shots till now and that too in 5x7
For storing I store them on Desktop,Laptop and external HDD....and a saperate folder for good ones which i may have edited ...and a folder for there original ones....also copy them on my Tablet.....soo good ones have 4-5 copies and all have 2 copies
Google drive and Google plus(picasa) is also good..as most of us have all our emails in Google system easy to keep everything in google drive and share with friends and family (using Google +)..sync is easy as you can install google drive/g+ app in your computer and mobile and access from all places and devices...
