I am reusing some code I found online, everthing does what I want except in Chrome two dots are visible in the lightbox when I click on an image in Chrome.
My experience in web design is very minimal, when I have tried to resolve the problem, it then breaks the functionality in IE8.
LightBox based on SlimBox2,
which was then modified by another developer.
my test page here
I have attached an image showing the location of the dots if it isn't obvious.
