Best format for attaching images in e-mail

The subject pretty much says it all. What is the best and most compatible format for attaching or embedding images in an e-mail? GIF, JPG, PNG, SVG, BMP, (etc.)? Are these read by all modern e-mail clients or are there some gotchas we need to watch out for? What about mobile clients (not browser-based)? How about formats that support alpha channels?

PNGs are not supported by older Lotus Notes (6.5, 7). Using alpha transparency and true color might cause problems (e.g. in older Outlook versions). Stay with the good old GIF and JPG and you are safe. And remember that GIF animations may (a.) play slow on mobiles and that they may (b.) show only the first frame in some email environments (e.g. Outlook 2007+). I would not rely on vector graphics. However, here's an interesting example that includes a fallback image.
