My bud in Colorado has informed me that all incoming mail at his facility is now copied and destroyed, with copies delivered to the inmates. Delivered copies include an image of the envelope. All photos on photo paper, even from third-party services like Shutterfly, are now banned.
This is a new contraband interdiction policy. Whether it applies statewide, I do not know, but my best guess is it would. Note that the feds have been doing this for years, except for the photo part... so far.
