John,

That's the only heading there (in IV - EXIF). [Try it to see what I
mean.]

Can't. XP, remember. Apart from not having IrfanView nor knowing which
version ofcourse.

Though see below.

I'm sorry, but I do not quite get which point you're trying to make there.

The only thing I see is that you recognise that each program does (and
shows) things its own way. Which is something I already mentioned.

Regards,
Rudy Wieser
