Does anyone know of a universal, one stop PNGFix script that isn't dependent on a specific library (like jQuery or Prototype?).
I just want to drop it in the header and have it take care of all transparent .png's from my stylesheets and markup.
Can't seem to find one that will do the job.
A non-library dependent one would be http://www.dillerdesign.com/experiment/DD_belatedPNG/
However you have to individually point out which elements should be targeted. There is never going to be a script that will fix every single png properly because there are so many position/layout scenarios and bugs relating to stacking order in IE6 that it's impossible to account for every situation which is why it's best to individually fix elements.
We used to use this at my company, until we finally moved off of IE6: http://www.twinhelix.com/css/iepngfix/. Just google "png fix" or "IE6 png fix" and you'll find dozens of resources. But as others have already warned, many of these cause more problems than they solve, and individual fixes are usually in order.
The best solution would be to not support IE6. Start lobbying with your company's IT department.
