I get an empty image with no content. There is no error, the image just 
doesn't display anything. Also, this returns false:

   put (the imageData of img 1) = (the text of img 1)

So they aren't the same, but each has its own purpose. If you need to 
manipulate pixels, use imageData. If you need to work with whole images, 
the text is more useful.
