With so many image formats to choose from, how do you know which one will work best for your documentation? Here’s a quick primer:
GIF
GIF images are usually very tiny – they are great for web graphics. Also, the GIF format supports transparency, something that also makes GIF images good for web applications (since it makes it easy to place irregularly-shaped images on top of patterned backgrounds). You can also create animated GIFs, which you can use for web applications as well as PowerPoint slides, but be careful – like the blink tag, animated GIFs can be very annoying when they are misused or overused.
