For removal of lag:

1)Put the images in res/drawable-hdpi if images are static.If it is downloaded from URL then use background thread for loading of images.

2) set page off screen limit by this method viewPager.setOffScreenLimit(size) . With the help of that view pager cache the minimum number of screen which you set in this method by default its value is 1.

3)You can use FragmentPagerAdapter and FragmentStatePagerAdapter for better performance.
