Hi
I have posted some post about this before.

But now the site is public, and we are getting a lot of feedback for people saying the the slider is behaving strangely.

Here are some errors:

1) Display in poor quality, if you view the img it is fine… http://screencast.com/t/ofnQW5EF

2) Loads in half size: http://screencast.com/t/CAuGUMmchAaW

3) doesn't load at all: http://screencast.com/t/MBZlaCen4T
