Okay, so I tried resizing some of the images at a lower res/smaller file size and the 5 that I put in for testing purposes are all below 50 kb. It does load way faster for me in Firefox now which was my next issue to address, but still does not load in IE
The website I got it from also says
Note: be sure to not include a ',' after the last line or you'll get an error in Internet Explorer.
However, I did try removing the comma, with no change... I tried using the exact script initiation code that they have there (I removed all the stuff for making the captions (animationStart) pop up to see if the problem was somewhere in there) but again no change.
I'm going crazy because if I copy and paste the exact script code from the example page with captions it still does not work in IE - even though their example does! I'm wondering if it's possible that something is wrong in my CSS? Or the doctype I used?
