From: ZB on
As I can see, there is available - since 8 years - GWImage widget written by
George Peter Staplin, which is displaying JPEG images just fine (and
quickly!).

Couldn't be possible - for someone more advanced in mixing C and TCL - to
"extract" the JPEG-related functions, to prepare something similar to tkpng
package - I mean: just adding "overall" support for JPEG ("image create
photo" ...and so on)?
