If the photos are included as an attachment, you should be able to click on the link that says "View Attachments," and from there you can save the picture file(s)to your desktop (or wherever).
Then, when you compose an email, click on "Add Attachment," and you'll get the dialogue box from which you can select any file(s) you wish to send.
It sounds like you received several photos? If they are each a seperate file (probably .jpg), just look at each to make sure you get the right one.
Hope this helps you.
