### Image
To load an image:
* tap **"Take Picture"** or **"Pick Picture"** menu button, or
* use the **Share** option of an app like e.g. Gallery.

* **"Pick Picture"**: Opens an image viewer app to select a picture
* **"Take Picture"**: Starts a camera app to take a picture
* **"Save as WAVE File"**: Creates a wave file in the Music folder in SSTV Encoder album
* **"Transform Image"**:
* **"Rotate"**: Rotates the image by 90 degrees
* **"Reset"**: Resets image rotation and scaling
* **"Modes"**: Lists all supported modes
