Weird javascript in svg image sources?

[Aaron-P]

Several of the svg images contain script tags defining a function for no reason that I tell. The function seems to be triggered when a property called "ysmm" is set on the window object, runs some sort of string decoding routine on the value, and then tries to do a redirect. I don't know what effect this may have for something that's being inserted into the browsers chrome, but it certainly seems strange.

The actual image itself also seems to be a png embedded into the svg, which I'm not sure why you would use a vector image format only for containing a raster image.
