POD is not a commercial and its no problems uploading anything , RM as well. The POD dont sell pictures like micro-agencies they sell prints and therefore not commercial as such.
I have to say though, it used to be good but today its like a graveyard!
At FAA you can opt in images, in bulk or
one one by one, to sell as either RM or RF. So far, I only remember reading Joanne saying she'd had a file licensed via FAA, way back when it became an option.
As always, you should read the contract for yourself to see if the terms are acceptable to you.
