Jim, your asking to add yet another token to the already large library, thus making things more complicated, rather than less. You can easily change and 'set' the size of an image and apply it to a button using the handler below. Note, this code could be easily modified to do a lot more, including error-checking, auto-changing the size of a button, etc.
See esp the line: set the imagedata of last img to the imagedata of last img
CREATE A NEW STACK CREATE A BLANK IMG NAMED "temp" CREATE A BUTTON "myButton" AND SET THE SCRIPT OF IT TO:
on mouseUp
constant kImgWidth = 80 answer file "choose image:" if it is empty then exit to top
makeAndSetIcon it, "myButton"
end mouseUp
on makeAndSetIcon pImgFileName, pButtonName
--> THIS HANDLER WILL SET THE ICON OF BTN pButtonName --> TO THE FILE SPECIFIED BY pImgFileName --> BE SURE TO HAVE AN IMG NAMED "temp" SOMEWHERE --> ON THE CARD (MAY BE OFFSCREEN IF YOU LIKE)
--> CHANGE kImgWidth TO CHANGE ICON SIZE
constant kImgWidth = 80
lock screen clone image "temp" set the lockLoc of last img to true set the resizeQuality of last img to best set the filename of last img to pImgFileName set the width of last img to kImgWidth put the formattedheight of last img into tH put the formattedwidth of last img into tW set the height of last img to kImgWidth/tW * tH
--> THIS 'FREEZES' THE SIZE OF THE LAST IMG set the imagedata of last img to the imagedata of last img
set the icon of btn pButtonName to the id of last img unlock screen
end makeAndSetIcon
and...

Hmmm.
Mathewson's problem can be fixed by adding a single statement after his two set width of img statements:
set the lockloc of img "Richmond" to true
