| height | number | Height of result image when used with `cropping` option |
| multiple | bool (default false) | Enable or disable multiple image selection |
| writeTempFile (ios only) | bool (default true) | When set to false, does not write temporary files for the selected images. This is useful to improve performance when you are retrieving file contents with the `includeBase64` option and don't need to read files from disk. |
| includeBase64 | bool (default false) | Enable or disable returning base64 data with image |
| includeBase64 | bool (default false) | When set to true, the image file content will be available as a base64-encoded string in the `data` property. Hint: To use this string as an image source, use it like: ``<Image source={{uri: `data:${image.mime};base64,${(new Buffer(image.data)).toString('base64')}`}} />`` |
| includeExif | bool (default false) | Include image exif data in the response |
| cropperActiveWidgetColor (android only) | string (default `"#424242"`) | When cropping image, determines ActiveWidget color. |
| cropperStatusBarColor (android only) | string (default `#424242`) | When cropping image, determines the color of StatusBar. |

| compressVideoPreset (ios only) | string (default MediumQuality) | Choose which preset will be used for video compression |
| compressImageMaxWidth | number (default none) | Compress image with maximum width |
| compressImageMaxHeight | number (default none) | Compress image with maximum height |
| compressImageQuality | number (default 1) | Compress image with quality (from 0 to 1, where 1 is best quality) |
| compressImageQuality | number (default 1 (Android)/0.8 (iOS)) | Compress image with quality (from 0 to 1, where 1 is best quality). On iOS, values larger than 0.8 don't produce a noticable quality increase in most images, while a value of 0.8 will reduce the file size by about half or less compared to a value of 1. |
| loadingLabelText (ios only) | string (default "Processing assets...") | Text displayed while photo is loading in picker |
| mediaType | string (default any) | Accepted mediaType for image selection, can be one of: 'photo', 'video', or 'any' |
| showsSelectedCount (ios only) | bool (default true) | Whether to show the number of selected assets |
