Ya if they exceed the fliesize limit, that is why. My new 7D files are to big to mail, thats the price you pay for quality.
Thank you for your reply. Apparently Windows Live for whatever reason does not allow sending multiple pictures! I was sending them regularly with NO problems. I switched to Mozilla Thunderbird and I don't have to do a thing to them and it sends them all as an "attachment"......but show up on one's scree "inline"......The Hell with Windows 7 Live Mail!!!
