With the release of IE 7, the consistent use of PNG for Web sites and Web applications moved closer to a reality. However, while recently experimenting with a few concepts that rely heavily on PNG, I discovered IE interprets the gamma (gAMA) data chunk contained within a PNG differently than other browsers. The image will render darker(i have encountered with it,and it takes me some time to fix it.), which can be problematic if you need a GIF or JPG to match the color profile of a PNG.
