Gets or sets a value indicating whether CMYK images should be resized or ignored.

## Syntax
 
```
$au.imageUploaderFlash({
    converters : [
        {
            //...other params...
            thumbnailResizeCmyk: false,
            //...other params...
        }
    ]
})
```

```
$au.imageUploaderFlash('uploaderID').converters().set(index).thumbnailResizeCmyk(value);
value = $au.imageUploaderFlash('uploaderID').converters().get(index).thumbnailResizeCmyk();
```
 
### Property Value
 
Type: **Boolean**
 
If `true`, CMYK images will resized by the browser. In this case, it may do it without color management (depending on the browser implementation). If `false`, CMYK files will be interpreted as non-images and therefore Thumbnail mode will fail. You should use it in combination with SourceFile mode as fallback.
 
Default value is **false**.
