The plugin seems to have issues on IE.
I've opened another thread as it is a different problem than the one described just two lines below this one.
It seems that only in IE the pictures in the gallery appear with a sort of foggy or haze effect on top of them, while in other browsers this is not the case.
This is the link to the live website: http://www.colormatics.be/kleurenaanbod/ where you can see the problem.
What can be done to resolve this?
