Avg Bid (USD)

$30 - $250

Project Description:
I developed a slideshow for a clients homepage which shows a caption on every other image. The problem lies in the slide show timing. Everything works fine for the first 8 images then when it loops back to the start the timing between slides speeds up so each images is on screen for less than a second. There also seems to be some cross browser issues.

I need someone to help me clean this script up and ensure it's working properly in IE8 & IE9.

Attached is the script that i'm using.

Skills required:
AJAX, HTML5, Javascript, jQuery / Prototype, PHP
Additional Files: slickslideshow.js
