I assume you're using mac mail ... If you have html view on in your email client, it's going to embed images.
To not do that,
In your email client, go to the top under View => Message => change to Plain Text Alternative
That should set your messages to text mode, so when you attach an image, it will not be embedded
Go ahead and switch it back to html.
Even though the picture is embedded in your email, you should be able to right click on it and save it as a file. Can you try that?
Go back in there...and choose always send attach at end of message. I believe this will create icons for the images instead. Let me know if that does it.
Hmmm...that should have done it. Were you in the middle of an email when you did this. Go ahead and close out of mac mail ... open it again, but make sure you're not in the middle of composing an email.
Mail, go to the Edit » Attachments menu, and make sure 'Always Insert Attachments at end of Message' option is checked
close mac mail and reload
