### Save a picture

To save a picture with the width & height that you have defined you must use the imageAsset and save it to the file system like so:

``` TypeScript
const source = new ImageSource();
source.fromAsset(imageAsset)
.then((imageSource: ImageSource) => {
const folderPath = knownFolders.documents().path;
const fileName = "test.jpg";
const filePath = path.join(folderPath, fileName);
const saved: boolean = imageSource.saveToFile(filePath, "jpg");
if (saved) {
console.log("Gallery: " + this._dataItem.picture_url);
console.log("Saved: " + filePath);
console.log("Image saved successfully!");
}
});
```

This could be used to create thumbnails for quick display within your application.
