if (the imagePixMapID of img "testImage") is empty then
   answer "Unable to open the selected image." with "OK"
end if


You can also get a little more creative and use QuickTime to determine 
if the file can be opened.  At that point you can go 1 further and 
convert the image to a format that Revolution can understand, and now 
you've given yourself the ability to open all image types that QuickTime 
can support.
