The Fullscreen Image Gallery Plugin is worth every cent you pay for it.
Beautiful photos deserve to be displayed in fullscreen, not in small boxes with fat borders and "next" buttons, that move to another position for every image you watch, making watching a large collection of photos a pain.
This is one of the very few gallery Plugins, that are capable to trigger the browser's fullscreen mode automatically and presenting your images using the entire screen real estate. Check out the demo!
Setting up the plugin is very easy and straightforward.
And what needs to be mentioned: Infyways' support is stunning. Within minutes I got a few beginners' questions answered, and when I asked for a new feature (sorting of images according to ascending file name), they immediately (meaning: also within minutes!) provided an update package with the feature working.
I won't hesitate to buy from them again, if need be.
