MBB,
It's a crazy world. When it comes to quality, especially with image files, the larger the size, and file, the better. Then when you want to share this with others, you have to reduce the size to something like 1 pixel by 1 pixel, otherwise it takes ages to up/download. Therefore in terms of sheds and chainsaws, there's little difference between a white cat in a snowstorm, or a black cat in a coal shed..
Personally, I'd use MS Office picture manager, and edit/compress the picture file to web page size, about 40-50 mb. Should be OK then.. Remember to save as "somethingelse.jpg", otherwise you loose that wonderful quality your 20,000,000 meg/pixel camera took in the first place..
Now we could be talking .wavs and .flacs v. mp3 here..
