Image sizing a problem...

[Jim Carwardine]

Jim... Thanks again for your help.  Here is the script that seems to work.
Setting the rect of image whatPosition seemed to do the trick.  I put back
the set icon statement to the short id of the image...

set the showName of button whatPosition to false
  set the style of button whatPosition to transparent
  put 43 into theTargetSize
  if there is not an image whatPosition then create image whatPosition
  if there is not an image "tempImage" then create image "tempImage"
  hide image whatPosition
  hide image "tempImage"
  
  put gGraphImg into image "tempImage"
  
  put theTargetSize/the formattedwidth of image "tempImage" into theRatio
  set the width of image "tempImage" to theTargetSize
  set the height of image "tempImage" to \
      round(the formattedheight of image "tempImage" * theRatio)
  if the height of image "tempImage" > 25 then set the height of image
"tempImage" to 25
  set the rect of image whatPosition to the rect of image "tempImage"
  put the imageData of image "tempImage" into tempResizedImage
  set the imageData of image whatPosition to tempResizedImage

  set the icon of button whatPosition to the short id of image whatPosition
