Photo Problems

I now have the following problems with my iPhone 5:

1. Cannot view photos sent as text messages; I have to send as an email and download.

2. Cannot view my photo albums.

3. Can only access my camera roll by clicking on the camera and then the camera roll icon on the left.

4. Photos and other images will not rotate when I rotate my phone.

Any suggestions? I have not found any solutions thus far.

Thanks!!
