Cheers RR - glad that's come in useful. Yep, a link to my site is best. I'll keep on bumping this thread when new stuff gets added (it will, I promise!)

CoyoteMax - that looks cool! Photoshop does have an annoying habit of autocropping transparent regions. That dot basis sounds like a pretty good solution, but certainly a time consuming one. I'd say that people may well be interested in the psd if you're willing to provide it.
