yeah.. I have a flickr pro account and I usually still reduce all my pics to 700px on their widest size, 72dpi and probably 6 or 8 in the jpeg quality slider. That's enough for most images on the intarweb. Plus I don't want people ripping off uber high-res files of my shizzle (and the uploads are faster, obviously).
edit: I had xnview on my pocketpc back in the day.
