I recently found our that some PNG files render a slightly different shade of color in Safari. (I think this is because Safari can't render PNG Gamma channel properly or what). 

How do I export the PNG images so that they work perfectly fine throughout all the browsers.
(preferable using Adobe Photoshop)
