Does zbarimg support qrcode?

The command man zbarimg doesn't mention it, nor does it's site, zbar.sf.net.

You could also make a separate script and call it from find.
That would make sense if this is something you do occasionally or often.
Maybe put this in ~/bin/tagimg.
I haven't executed this, but it looks right.
Code:
#!/bin/sh
if [ -f "$1" ]; then
    $TEXT="$(zbarimg -q -Sdisable -Sqrcode.enable --raw "$1")"
    exiv -M "set Exif.Image.DocumentName '$TEXT'" "$1"
else
    echo "File not found \"$1\"" >/dev/stderr
fi

(Note that '$TEXT' gets expanded properly because the single quotes are inside double quotes.)

Then the find command becomes
Code:
find . -name '*.tif' -exec ~/bin/tagimg {} \;
