1. Put your cursor where you want it in the document window.
2. Select Insert>form object>Image Field
from the main menu.
Or click on the form button in the object panel: form section:
3. In the dialog box, navigate to the image that you want to use (you can also
change your source to any image URL on the web)
4. In the Properties panel:
-give it a name.
-give it width and height if you desire
-in the src field you point to the URL: local to your site (relative) or a
full web address: "http://www.address.com/image.gif" an absolute url.
-put in alt text in case a user cannot see the image
-select browser alignment for the image.
