##	0.1 - First Version (rewrite of old gallery script)
##	0.2 - Fixed pause to pause as soon as clicked
##	0.3 - Automatically insert fist large image, no need for markup
##	0.4 - Fixed auto-scroll to scroll when the last thumbnail had finished it's time
##		  Removed some useless code which put the thumbnails into groups using classes
##	0.5 - Fixed problem with finding correct offset for the hover image to appear
##	0.6 - Remembered about nth-child, got rid of now useless code
##	0.7 - a few fixes, scrolling the thumbnails now pauses
