If it is not working from contacts app then we have reverse maping

Just Go to Gallery, Pick any picture and go to options "Set as/Contact icon" and choose desired contact.
Simple solution: Go to Settings/Accounts/Facebook/
Now
Turn off Live Feeds. And Remember now
don't try Pull to Refresh when you're on Gallery, Otherwise it will again Refreshed.
Sorry you can't remove this pics.
Mostly Its about your Battery issue. Maybe you need to change ROM and see if this problem occurs, Nobody have this issue, so definitely not a ROM bug.
This app might help you~~~>

Glad you find your issue.

Hope you'll Enjoy Sense 5 more and more.
You can't disable delivery report sound, But you can disable Delivery reports from SMS Settings
Menu buttorn support is nothing but you can access settings/venom hub/tweaks/personalise options by pressing menu button on home screen as you have already done in old Viper Roms.
BlinkFeed is just Social+RSS Reader. That's it
Simple Reboot may solve it, if doesn't work then Reflash, Something is wrong at your side.
You're talking about BlinkFeed and Home screens, The Answer is No. You can't change the order. NOTHING IS MOVABLE.
Radio/RIL have nothing to do with bootloop. maybe you're S-ON or you're running old recovery.
First, Sync with Facebook works like Charm, No need to have any 3rd party app at all, If picture on contact is unclear you just click and open the contact for a while, it will get clear.
Thank you all.
