I don't think libexif should be added to the jpeg loader - libexif is
used by gphoto2, gtkam, and a couple of smaller projects. No need to
duplicate about 7237 words (wc). Linking? Don't know if it is worth the
trouble.

I didn't know gdk_pixbuf_get_option. I don't think it is very useful in
this context. Take translation for example - libexif has translations
for the tag names and values. You can iterate over all available tags.
You can modify them.

I'd go for using libexif in the frontends, i.e. adding code to EOG to
check for EXIF data and display it in the status bar as banner.
