The "text" of the image is the actual image data as you would find  
stored in a file on disk. So if you need to save an image to disk and  
open it in Photoshop you could store the "text" of the image to a file:

put the text of image "MyImage" into URL ("binfile:/Users/Mr User/ 
desktop/my image.png")

The imageData is the data that is displayed on the screen.
