I use BMP or raw actually files that come out of my camera, but they are resized and cropped with other adjustments before they are saved in a jpg file for uploading to a web, I also sometimes use png files as they are actually better in color handling, but for general web use and if others I don't know will be viewing the photos then they are ALWAYS jpg files.
