Android picasso image resize

Calling the android picasso library and passing image dimensions into the resize method

We return to the origins of this tutorial series and call the android picasso image resize feature. If this is not used picasso will load the full images. Which will have an obvious impact on the scrolling speed of the android recyclerview image gallery.
