Enlarge a photo

I use the camera component to take a picture and display it in a horizontal layout. I would like to be able to tap the pic to make it full screen. Also, how do I save it to my SD card so I can view it without using the app.

I already searched enlarge an image. Only 1 post came up and it wasn't relevant.

Post the aia (and also the blocks).

here are the relevant blocks.
