Remove option to lazy-load images (#2365)

Remove option to lazy-load images

Lazy-loading option is introduced through the 'eager' prop in and components.

Images are loaded as scrolling occurs, resulting in inaccurate scrolling as seen in issue #2364.

Let's remove 'eager' prop from and components

All images are now loaded eagerly.
