AOL webb users cannot download photos from iPhoto

At last my husband can send photos via iPhoto by using the mail button. However, his AOL web email friends cannot download these photos.
Is there an easy way to send photos, via Apple mail and iPhoto so they attach to the email and not embed into the email? Thanks.

Try right-clicking the image in Mail, then select the Show As Icon (I can't remember exactly what it says in the contextual menu, but you'll see it). It basically turns the embedded image into an attachment.
