Hi!
I thought this could be the platform to reach the devs of PowerPoint fastest and most easily.
Hoping that someone working on PowerPoint sees this.
But here is my suggestion :)
Currently there is no way to change the transparency of a picture as a whole.
If adding that feature is feasible adding a control (a slider or such) "Picture Tools"-tab would be awesome.
ATM, you actually can adjust the transparency of a picture (it is a clunky workaround) but the process of doing has too many steps and is really uninuitive.
