Which is essentially what I ended up doing, and it worked. Is it  
correct to assume that 'the text' is binary data expressed as ASCII  
text and data like 'the imageData' is "lower-level" code that can't  
be expressed visually in a meaningful way? Forgive my naive non- 
techie questions.

Am I correct in my understanding that these two statements are  
functionally identical:

	put myData into image "myImage"
	set the text of image "myImage" to myData

?

In other words, 'put' is simply shorthand for 'set the text of  
<object>'?
