Putting a breakpoint on the call to DoResizeStack does not prevent the

with the debugger failing, I can't figure out what is going on.
Any hints?
There are a lot. ;) I'll comment your script:
on resizeStack
DoResizeStack -- this is a command handler call, not a function
end resizeStack
Command handlers are written the way you have done it. Functions
generally return a value to the calling handler are are written in this
format: put myFunction() into tResult. If there are values to be passed
to the function, you add them inside the parentheses: get
myFunction(val1,val2) into tResult. Note that functions must be called
with a place to put the returned value; i.e., my example uses the
varialbe tResult to store the returned value of the function call.
Your command syntax is appropriate; you should not be using a function
here. So what needs to change is your handler syntax, like this:
on DoResizeStack -- using "on" makes it a command handler
set left of "image" to 8
-- here you have not told Rev what object to operate on. What is
"image"? You can refer to objects by name, ID, or number, but you need
to indicate what object should be manipulated. The line should be:
set the left of img "imgName" to 8
or you could use:
set the left of img 1 to 8 -- OR:
set the left of img ID 1005 to 8
Any of these will work, but you do need to let Rev know what object you
are setting.
The same applies for all lines in the script that use "set":
set the top of img "imgName" to 20
put the width of img "imageName" -16 into ww
put the height of img "imageName" - 32 into wh
put the formattedwidth of img "imageName" into fw
put the formattedheight of img "imageName" into fh
put fh / fw into iRatio
put h / w into wRatio
if iRatio > wRatio then
-- image is taller than space available: need empty space to right of
image
set the height of img "imageName" to h
put h / iRatio into w
set the width of img "imageName" to w
else
-- need space under image
set the width of img "imageName" to w
put w * iRatio into h
set the height of img "imageName" to h
end if
end DoResizeStack
I have added "the" to all the properties referenced in the script, that
is, "the height", "the width". Technically this isn't necessary but I
find it to be good form.
I am not sure why Rev would hang -- you should have seen a syntax error
somewhere I think. But I suspect it didn't know what to do when you
called a command handler but wrote a function. Just a guess.
