Putting over 100GB of photos on your phone/tablet

How many people here are interested in carrying a large number of photos (a few hundred GBs) on your phone or tablet? Do you often show off your awesome photos to others from your phone?

Generally phones and tablets have limited space. Let's say an app can automatically sync a resized version of your photos to your phone (so it won't need too much phone space). Do you think it is useful?

p.s. I am an app developer and trying to figure out the interest level in this forum.
