It's also important to know that imageData and the content of an 
image (its text property) aren't in the same format.

The imageData is an invariant format that provides the RGB data for 
each pixel. The text of the image is the image's data in whatever 
format - PNG, GIF, JPEG, or whatever format the image is encoded in.

Normally, if you get the data from some other source, it will be in 
PNG, GIF, etc., so you'll use a statement like
   put myImageData into image "My Image"
Only if you're modifying the image data yourself do you use the 
imageData, usually.
