Hi all,

Can you explain this?

With your Canon digicam take a picture, download it with Zoombrowser, save it in to your HD, use Zoombrowser to upload it into your camera again, select the same image size to avoid picture-resize during upload, then download it again.
Now you have 2 "equal" pictures on your HD, but check the file sizes... is about 30% smaller!

-what is happening?

one thing you lose is the picture information like ISO speed, shouter speed and so on
