how to determine the size in between the thumbnails (javascript/jquery slider)?

A working sample here:

http://www.asstatauka.us.lt/slide/header2.html

I do not know how to determine the size in between the thumbnails (it shou开发者_JAVA百科ld be three thumbnails close to each other). Also, how to display image title not only for the active thumbnail, but for all thumbnails? Please advice.

I am using: https://github.com/wandoledzep/bxslider/blob/master/source/jquery.bxSlider.js
