Image File Information

We talk about image file types quite a bit in class and I thought some of you might be interested in learning more about some of the types beyond .jpg and .gif, so here's an excellent article on it:
It is a little technical, but even if you just look at the pics, you can see some of the differences between formats.
A quick summary:
  • .gif and .png have the ability to have transparency.
  • Only .gif can be animated.
  • .tiff is superior for amazingly high quality.
(The picture above is a screenshot of a .tiff file.)
  • .jpg is the most commonly used due to it's good quality, yet small file size.
  • .bmp has huge file size and thus is rarely the best format to use. An exception would be that it is a Windows wallpaper format.
