No, there is no way to directly move an image from the Picture Box to the CWIMAQ Viewer and back. The reason for this is that the CWIMAQ Viewer requires a different image data structure than the picture box. It is not possible to read a file with the LoadPicture command and then send it to CWIMAQ Viewer. You must read the file with one of the Vision tools to read files such as CWIMAQVision1.ReadFile.
I hope this clears some things up for you.
