Kalypso, are you on a MAC? If so you NEED to get the utility "ZipIt" It is free, but limited (You pay some money to unlock things like encrypting) http://www.maczipit.com Some of my clients have had the problem with not being able to unzip things on the MAC side if they don't have ZipIt. Since I zipped it with this program. Back to the large file sizes. It's not me, I was noticing someone else had uploaded large thumbnails. Could be bmp, don't know. Forum moderators need to look into this. James
