Go to Messages, click Manage Images. Click View Contents next to the Image Directory for which you’d like to view the images. The screen will refresh and the images will appear on the lower half of the screen.

Find the image you’d like the url for. Copy the url in the field Image URL for the image you wish to use. If you will be placing a few images in your email, you might open Notepad (or Text Edit on a Mac) and copy and paste all the urls of the images you’d like to use onto one page to make inserting the images into your email more efficient.
