Hmm. Not sure. The image, of course, has to be in a format that RR can 
read (jpg and gif are most common). Maybe the image you are choosing is 
too large, in terms of bytes? I'm not aware of any size restrictions per 
se, but if you are trying to load a huge image it might monopolize 
memory somehow. Usually the images I load are very small, like little 
bullet pictures or small arrows. Most are only a few kilobytes or less. 
What happens if you choose a very small image?

In the test I did, I just created a new field in a new stack and put a 
few characters of text into it. I didn't change any of the field 
properties. Then I used the script above to set the first character's 
imagedata. Did you try it with a new field?

The fixedlineheight doesn't seem to matter. In my test, the field 
originally had fixedLineHeight set to true but the image got chopped off 
at the top. So I set it to false and the image became fully visible. So 
that part seems to work either way.
