Be a little careful on the above. Viewing an image on a low resolution device like a monitor (CRT or LCD) doesn't require a high resolution image. Low res and high res look the same. However when you go to print an image it can be a different story. Printers these days are capable of very high resolution. It's said that to be "perfect" you need 300 pixels for each inch of print size. So following that "rule" an 800 x 600 pixel image would only be 2.66" x 2" in size when printed
while the original (2500 x 1875) could be 8.33" x 6.25". Generally I find you can get by with 200 pixels per inch, and sometimes less, without seeing too much in the way of pixelation (small blocks in print). It depends on the image in question and how picky you are. I always save the original image, plus any modifications I make, as 2 separate files in the resolution that came from the camera (no resizing) and either w/o any compression or with the least amount of compression. If I want to send somebody a low res picture or post one on the WWW, I then resize and compress it (3'rd copy) as needed. I can always delete this last copy to save space and recreate it again if/as needed. This does chew up disk space but disk space is cheap to add these days and I'd hate to change a picture that I later might want in "high res" format. Once you've resized a picture to a smaller size you can't go and reverse the process and get back the same high resolution picture you had before. Once you've compressed a picture you can't get back the same picture you had before compression.
Edit : Ha ! Looks like Island-Ho and I were typing at the same time (though me a bit slower
)
