How do I post a photo?
To upload a photo or take a new one, first tap 
at the bottom of the screen:
- To upload a photo from your phone's library, tap Library at the bottom of the screen and select the photo you'd like to share.
- To take a new photo, tap Photo at the bottom of the screen then tap
. You can tap 
to switch between front and rear-facing cameras and 
to adjust flash.
Once you've taken or uploaded a photo, you can add effects or filters, a caption and your location before posting. You can also post a video.
Note: You can't take or upload photos from a desktop computer.
