Does anyone know of "before and after" gallery tutorials?

Hello,

I have seen many tutorials on how to create xml-driven, thumbnail-based image galleries, but I am looking for one which can do a “Before and After” photo effect.

I’m designing a realtor’s website and want a “before and after” gallery to show work being done on some homes, before construction and after construction.

So, basically, you have two photos, same size, overlaying each other, and use maybe an Alpha fade to “merge one photo into another”? Something which slowly fades one into another, not just something which does a complete Alpha fade out, then a complete Alpha fade in.

Anyone have any ideas or know of any tutorials which do this effect?

Thanks, Dave.
