How can I place scale measurements on macro photos Please ?
I am getting into 5x macro with the Canon MPE65 lens which I like a lot & I have ordered a 10x microscope objective.
I want to crop some images & add a scale measurement to the photos ?
Are any of the free to down load programs able to do this ?

If you're using a 10x objective you're only going to need to measure this once, right? Your magnification and focusing distance won't change. I would take a photo of a transparent scale ruler & superimpose as needed. Or maybe (likely) I'm missing something.

Ah I think I understand with the cropping/scale vs actual measurements reading other replies. We've usually just adjusted the ruler image and added text for how much that represented. It looks like you have a promising lead in this thread.
