View large images up close using simple mouse interaction, and the full screen.
Add full-screen-image class to image. The one mandatory attribute is either a src, data-image or a href, which needs to point to an image file. You can use data-image if you want to load in a different version of the image to the original source (higher resolution, for example).
You can also pass through titles, and subcaptions, which will appear at the bottom right of the viewer. To do this, you use the data-title and data-caption attributes.
This plugin is based on Intense Image Viewer javascript liabrary by Tim Holman

Simple Full Screen Background Image will allow you to easily upload and set a full screen image as the background of your website. Images will be automatically scaled with the browser, so regardless of the browser size, the image will always fill the screen, even as the browser is resized live.
Once activated, go to Appearance > Fullscreen BG Image. From here click Choose Image, then either upload from your computer or choose one from the media library. Once you have chosen your image, select the size you wish to insert and click Insert Into Post. A preview of your image will appear below. Now click Save Options 
and view your site. The image should now be applied as a full screen background image.
