Could you elaborate a bit on your problem? Did you previously have the IMAQ ImageToArray VI working with an I16 output, but now it no longer works? Is there a broken wire coming from the output? What changes were made since it was working? This information should help us hone in on the issue. In the meantime I found a forum pertaining to a similar issue (http://forums.ni.com/t5/LabVIEW/IMAQ-quot-image-to-array-quot-directly-wired-to-quot-array-to/td-p/2...). Have a great day!
