Hi John,

since ImageJ handles the error condition of having no image by
displaying a notification box, the python try/except does not catch it.

Simply check at the beginning whether at least one image is there, e.g. with
   WindowManager.getImageCount()
An alternative is
   WindowManager.getCurrentImage()
which returns null if there is no image.

I cannot find a way to get either the window manager or the “Close All”  to dismiss the notification. I’ve shuffled them around and no matter where I put them, I still have to manual close the “No Image” error window.
