Hi @Mary Helen
Thank you so much for contacting Microsoft Q&A Forum.
Based on what you've shared, I understand your problem perfectly. You're on Outlook for Mac, and when you drag and drop a JPG file, it embeds directly into the body of the email. As a graphic designer, you need it to attach as a file, and this problem has been happening since a recent update.
I've tested this on my environment, and you're right: if I drag and drop a JPG file into the main content area, it embeds it instead of attaching it.
However, I did some testing and found a workaround you can try:
Try dragging and dropping the JPG file directly onto the "Subject" line (the subject text box), like I've highlighted in the image below.
In my environment, when I do this, it successfully adds the JPG as a file attachment, as you can see in this second image.
Please give that a try and let me know if it works for you.
