email/pic format problem

Question

A client sent me some vertical pics but they show up on my server as horizontal images. I viewed them via the browser -did not use an email client to view them. I forwarded his email to him and he says when he opens it the images are vertical. I don't have a clue.

Answer 1

If the images are in jpg format, it is possible that your client uses a viewer which rotates images according to orientation field in exif data.
