If you are using OE6 you should be able to right click on the photo You should then get the option to send by email. When you take this option there should be a choice menu to either send as is or reduce. I hope this is what you meant.
I mean when I highlight a photo in my picture and click on email this picture, I no longer get the reduce this picture option pop up. sorry Ive been so long replying to all, but I have been away for a week.
