Anyone know how i would get the covers to fit slim dvd cases?
You have to edit it yourself, or write a script for an image editor.
A script that grabs the spine, and adjusts its width (of course this will shrink/squish all the text&graphics).
I think you can do this with irfranview whatever free software.
Of course you could all ways write a more complex script that gets rid of spine all together, and then generates a new spine.
(this script would need a source .... presummily file name.... to grab text from to add to spin).
