Beginning Of Image Filters

I began image filters. I'm not totally sure how to implement them
though. Basically, I just made it so that on the creation of an image,
it also creates a respective CSS file in the SAME file as the image. I
also made a link for the respective CSS file. I cannot, however, figure
out the workings of webkit filters. I am including a link for you.
