I /think/ we are talking about different things here. I was proposing an
interface to use to create different ways to visually compare two
already loaded images. Not loading new images.

For image-loading this makes sense, for comparisons this would be (imho)

Exactly. But there are many different ways that you visually might want
to diff two images. It could be a mode for highlighting few but slight
changes, or one to show the difference (pixelwise subtraction) between
two images, or showing emphasis on color changes, or, or, or. Therefor I
was suggesting how to make a TIDiff-internal hard coded interface to do
this in an orderly (and pretty easily extendable) way. :-)


PS. For loading, DevIL seems nice, yes. DS.
