A:AnswerHi joflee1324, you can take selfies by setting the camera to self timer. But the LCD screen doesn't flip or tilt to allow you to see what yourself before taking the shot. Thanks_Mitch
A:AnswerHi Ro, yes, you can also transfer images stored in this camera to a computer connected to a wireless access point or wireless broadband router and easily make backup copies. Dave
A:AnswerYes, it has a rechargeable battery. It is in the camera and it has an attachment that you plug into the wall. It lets you know when it is recharged.
