Paul,

I'm sorry: I forgot a very important line in the handler I proposed:

on SetImageSource pImageName,pField,pChar, pHeight
   create invisible image
   set the botright of last image to -1,-1
   put image pImageName into last image
   set the lockloc of last image to true
   set the name of last image to pImageName & "Thumb"
   set the height of last image to pHeight
   set the width of last image to (the width of img "Ref" / the  
height of img "Ref") * pHeight
   set the imagedata of last image to the imagedata of last image
   set the imageSource of char pChar of fld pField to pImageName &  
"Thumb"
end SetImageSource

The important line to add is: set the imagedata of last image to the  
imagedata of last image
This allow to reduce the size of the"thumbnail"  image to its actual  
size: 2 KB  or less whatever can be the size of the original image :-)

Best Regards from Paris,

Eric Chatonet.
