Right click on the photo and select "open with microsoft office picture manager". Then select"edit picture" and select "change picture size" and "resize". Select "small for email" in the "predefined width and length" option. You can also select which part of the photo you want to be included in the avatar, by going to "edit using these tools" and selecting "crop", then cropping to your heart's content.
