Interesting information:

The GIF file format has allowed portions of images to be transparent, allowing them to appear to have a shape that is not rectangular. However, the GIF method was considered to be rather poor because it only allowed individual pixels to be fully transparent or fully opaque. The PNG format improves upon this by also supporting an 8-bit alpha channel, so pixels in an image can have partial transparency. However, it took a long time for web browsers to fully support transparency, and some, notably Internet Explorer (for Windows), still do not.
