I decided to try this rom out loving it so far,
But if I may I have a few questions.

1: how do you change the background images I would like to have custom images
2. I noticed when I hit the side volume buttons I do not get an image instead I get like corrupted data image like doesn't show anything but just noise almost like a severely heavy pixelated image

thanks ahead of time the 1 question is a must I want to have a picture of my dogs and my wife
