BoYo's solution is fine if you have just a few images, but more than a few images will require a more sophisticated solution, particularly if the images are at higher resolution (as you'll need if you want to be able to zoom in). Images can consume a lot of memory, so you'll want a strategy for loading only the images you need at any given moment and unloading them as you no longer need them. UIScrollView provides for tiling the content, so you can provide the scrolling content just a little at a time. That lets you keep only what you need in memory while still giving decent scrolling performance.

Take a look at the PhotoScroller sample code to see how this can be done well.

One solution for the scrollview is to create an UIImageView for every picture you want to add to your scrollview and then add them as subviews to your scrollview.
As far as for the tap part - you can create your own GestureRecognizer for the tap action and set anything you want to do with the selected image. Also try to change minzoom and maxzoom of the scrollview's contentview and zoom action will be added automatically for you.

NSArray *images = [NSArray arrayWithObjects:
                   [UIImage imageNamed:@"1.png"],
                   [UIImage imageNamed:@"2.png"],
                   [UIImage imageNamed:@"3.png"],
                   [UIImage imageNamed:@"4.png"],
                   [UIImage imageNamed:@"5.png"],
                   nil];
