sizeall not working for me. I tried with my phone. It was almost right size when loaded but when I clicked "Actual size" it was 1.4 times bigger than actual.

Check if correct monitor size is selected (in upper right corner).

Yes, that's better. That control was in my blind spot. Maybe you should do something about that.

Sizeall That's a cool idea, how do you get the images?

Thanks :-). I get images usually from the manufacturer website.
