Setup a Scrollbar?

If you are working with a scrolling field, the thumbSize adjusts 
automatically to the amount of text in the field.  Create a scrolling 
field with the formattedHeight of the text = to the the field's 
adjusted height...there will be no visible thumb.  Add one line of text 
and you have a fat thumb that gets slimmer with each line added to the 
field.

If you are using a scrollBar control instead of a scrolling field, this 
works for moi:

set the thumbSize of scrollBar "Index Scroll" to 
trunc(maxSize*(visibleLines/linesOfImages))
get visibleLines * imageHeight
set the pageInc of scrollBar "Index Scroll" to it
set the lineInc of scrollBar "Index Scroll" to imageHeight
