Preferred image size in email.
What is the preferred image size to be sent in the body of an email, when prompted by my iPhone to choose, small, medium, large, or acuaL? I'm asking really what size an employer would like to receive, as I am sending headshots to a casting company. Keep in mind the physical copies of my headshots have been sent through snail mail, so I'm looking for the size that is easiest for the employer to receive/handle for the same images through email. Thanks so much for your help!
