I have a JPG image of X by Y.
If the height of the image is greater than (for example) 700 then to split it into an another image,
Therefore if the image is 1400 in height, there would be 2 new images of 700 high
(This would of course be anything up to 5 images)
IF anyone can help this would be great, in fact I will give you loads of points if you put this as complete as possible :)
