If I create a pristine image I can get the alphaData and do 
reasonable things with it.  I can get it with these:

put the alphaData of image "Test Image" into x
put the alphaData of image "Test Image" into field "Image Data"

However, after I paint on the image, "put the alphaData" copies a 
bad string.  No, I don't mean the bytes were not what I expected, I 
mean the string itself did not behave as I expected.

"char 1 of the alphaData ..." and "the length of the alphaData..." 
seem to work OK.  The problem seems to be after the copy by "put".

In one case of a 4X4 image, 15 characters showed up in the field 
display, but the length returned 4 (should be 16).  I could 
right-arrow over the characters but left-arrow got stuck part way.

In one case of a 50X50 image, lots and lots of characters showed up 
on the screen but the length was zero.  The value acted empty for 
"char 1 of" and other functions, too.  A variable acted empty also.

A quick test showed a similar problem with imageData.

I think someplace in here is a bug.
