The images I insert to the comparison slider become pixelated? Why?

Hey… Nice plugin. Thanks! I just found it and started using it on the homepage this site I’m revamping for a client:

It’s a little buggy .. though. Sometimes the images disappear when you navigate off the homepage and go back to it.
Also… your upload script only works if you add the images into the media area in advance of trying to use the editor to add it to a page.
Thought you’d want to know
Best,
Mike
