[jQuery] .png transparency in IE 6 and jQuery

[FranktheTank]

I have been able to successfully apply transparency fixes to
transparent .png images using some jQuery plugins (as well as other
methods).  However, I have a problem in that my design requires that I
have rollover images on those .png files.  The problem is that every
method that I have encountered changes the src attribute in the code
so that it becomes blank.gif or pixel.gif - something like that.  This
is causing problems with other parts of my code where I need the src
attribute to be set to the original value.

Is there any method for achieving .png transparency in IE6 browsers
_without_ changing the image name in the source?

Thanks,
Frank
