This line of code: 

```
<input name="img" type="file" accept="image/*" capture="camera" onchange="uploadImage(this, 75)" />

```

fails to pass the [W3C HTML5 validator](https://validator.w3.org/) check:

I would appreciate anyone letting me know why the error from W3C (and any solution), given that the code works fine and it opens the camera for mobile devices.
