Script your grouped image with the following.
local iAmDragged=false
on mouseDown
set lockloc of me to true
put the loc of me into iL
put item 1 of iL into i1
put item 2 of iL into i2
lock cursor; set cursor to hand
put true into iAmDragged
dragMeInGrp i1,i2,the mouseH-i1,the mouseV-i2
end mouseDown
on dragMeInGrp L1,L2,dx,dy
if not iAmDragged then exit dragMeInGrp
if the shiftkey is down then -- drag only horizontal
set loc of me to (-dx+the mouseH,L2)
else if the optionkey is down then -- drag only vertical
set loc of me to (L1,-dy+the mouseV)
else -- drag in both directions
set loc of me to (-dx+the mouseH,-dy+the mouseV)
end if
send "dragMeInGrp L1,L2,dx,dy" to me in 8 millisecs
end dragMeInGrp
on mouseUp
unlock cursor; put false into iAmDragged
end mouseUp
on mouseRelease
mouseUp
end mouseRelease

I made a loooong rectangular image (3 times wider than my stack) and
grouped it
into a group the width of my stack and gave it a horizontal scrollbar;
so I can scroll the image
laterally using the scrollbar . . . surprise, surprise; and jolly s*xy
it looks too.
I would look even s*xier if it had NO scrollbar and I could do some sort
of
'constrained grab'/scroll by doing a mouseDown & horizontal drag on the
image within the group.
Does anyone know how to do this.
Just to stimulate interest, the reason is that I want to do this sort of
thing
in Livecode: http://www.stefanv.com/calculators/aristo970/index.html
