Is there a widget that can display a .jpg / .png / etc - preferably with some 
scaling ability?

See:
     http://developer.gnome.org/doc/API/2.0/gtk/GtkImage.html

and see gdk_pixbuf_* functions for basic functionality of scaling/compositing
and I think there was some rotation support added, not sure if it made it
to GTK+-2.4 though.

Rotation by multiples of 90 will be supported in 2.6. 
Note that for jpegs, you will likely want something else,
since jpeg->pixbuf->rotated pixbuf->jpeg is a lossy transformation.
So at least if you want to save the rotated jpegs, you should
try to rotate the jpeg coefficient matrix directly. I don't
know if libjpeg supports that, though.
