Once the Claim Status dialog appears, click
on the Start NEACOMM Now
button.

In NEA, double-click on the claim to which you would like to attach multiple images.
In NEA, be sure that the
Screen Capture option is
selected on the title bar and then click on Screen
Capture.

Bring the XrayVision application to the foreground.
Click on the Draw Rectangle button and click-and-drag around the image that is being displayed in XrayVision.
Repeat steps 5 through 7 for as many images as you would like to add to the attachment.
