Potential hacked css files of Lightbox Plus Colorbox

Hello,

I’ve just been looking into a few of your style css option files and I’ve found a few base64 codes amongst the background-image css that I thought you might want to know about.

Great plugin by the way, I was just wondering why some of the css was off and it seems this is why.

An example is:

blue Line 33 of colorbox.css
#cboxPrevious{position:absolute; top:50%; left:5px; margin-top:-41px; background-image: url(data:image/gif;base64,AAAA); width:49%; height:100%; text-indent:-9999px;}

blue Line 35 of colorbox.css
#cboxNext{position:absolute; top:50%; right:5px; margin-top:-41px; background-image: url(data:image/gif;base64,AAAA); width:49%; height:100%; text-indent:-9999px;}

This code is present in the style options of blue, black, burgundy, green, grey, navy, purple, red, teal, white, yellow
