Setting the text of an image is the same as "putting" one image into 
another, so it fails the same way my original suggestion does. I didn't 
realize you just had binary data stored. That does make a difference.

I think your best option is to write the binary to a temporary file on 
disk and then load it in as an image reference. There have been some 
discussions on how to get the dimensions of an image stored as binary, 
but they're all much more difficult than just letting the OS figure it out.

Use the tempname function to get a temporary file name. If you want to 
reuse the same file repeatedly so you don't have to worry about deleting 
it and making a new one, store the tempname path the first time and just 
keep using it over and over, replacing its contents each time.

Off the top of my head (you'll probably need to adjust this) do 
something like this:

   put the tempname into tTempPath
   -- extract your jpg binary data & put into a variable here, then:
   put tBinaryJPGData into url ("binfile:"&tTempPath)
   set the filename of img 1 to tTempPath

I think that should work. Temp files are removed by the OS at intervals 
so if you forget to delete it, it doesn't really matter.
