XnView Software

I imagine this has a simple answer. The default install comes with a label called custom2: {Width}x{Height} - {Size KB}. I'd like the size in MB, but when I changed the K to M that doesn't work. Any thoughts?

in : "Tools, Settings, Thumbnail, Labels", choose (or add) a Custom label
at the bottom of this window, set the mouse cursor at the end of the string of the custom label

press the >> buttton
select "image", and "Mpixels"
add also a text : Mbytes
is it right ?

Thank-you. That didn't help, but it helped me understand things a little better. It turns out that what I was looking for was size(auto) which shows MB when the file is bigger than 1 MB and KB when smaller.
