Answer 1

Start with a scroll view and add each image in an UIImageView as a subview to the scrollview at a certain location.

One thing to have in mind is to only hold in memory the images that are currently shown and their immediate neighbours.

What you have to do is create your scrollview however you want. You have to decide whether you want a grid layout, or linear layout. In addition, if grid, do you want it locked to the horizontal bounds, locked to vertical, so it scrolls either vertical or horizontal, respectively.

Once you have that sorted out, then what I recommend is taking the architecture similar to how a tableview functions. That is, create individual "cells" that will hold your thumbnails. Once you have these cells, you add them as subviews of your scrollview, at certain offsets (you need to do some math on the x/y planes).
