Some heatmap tiles do not load in IE

Not sure why.
Example got to http://coolstufflist.com/heatmap. Zoom out of California. You will see some tiles not loading

Problem might be that IE8 only supports 32,768 characters in data uri.

I looked up Data URI on wikipedia and I found a link to this.

"Data URIs cannot be larger than 32,768 characters"

Possible solution. Make an echo type web service where we sent the long data uri an it will return the png image.

Another solution. maybe try using a jpeg instead on png.
