I'm working on a website which will use images in several different applications, from action buttons to avatars to larger detail images. What factors should I take into consideration to decide whether these images should be jpgs, gifs, or pngs?

Obviously give each image a try and see what comes out to the smallest file size. The smaller the size the better. Also don't worry about transparency in IE6 for your PNG's, grandma isn't as concerned how your site looks just that she can see pictures of you on it. |

File size. The smaller the file size the faster it will download for your users. So go for the smallest file size that doesn't affect your image quality. (Generally speaking JPGs are used for photographs and PNGs/GIFs are used for icon-like images) |

Browser Support. I think it's IE6 or IE7 and older do not support png based images with a transparent background properly. It usually adds some funky background color. |
