However, if you save an image as a PNG then upload it to the internet, it experiences a slight problem and makes your image slightly darker. Not noticeable at first, but if you keep doing back and forth, it gets darker and darker.

But there is a solution, if you save it as a BMP but upload it to Imageshack, it automatically converts it to PNG without altering your colors.
