How to access a local file from a Chrome app?

Question

JavaScript

I am writing an application for Chrome, I save the images added by the user to the database, or rather links to them, so that the user can continue working with them later. But the images are not displayed in the application window.
If you get the links in their pure form: "C:\Images\myjpeg.jpg" Chrome gives the following exception: "Not allowed to load local resource: C:\Images\myjpeg.jpg (if you add file:///, the situations will not change ). Ok, it turns out that you need to turn links into a File object, and then into a special URL object and then display, but for some reason this does not happen. It forms a link, it is attached correctly to img, but is not displayed.

var newURL = window.webkitURL.createObjectURL(new File([],"C:\Images\myjpeg.jpg",{type: "image/jpeg"}));

In theory, such a code should give the correct link to display in img, but am I missing something or not understanding correctly? Maybe the file object needs to be created somehow differently for createObjectURL()?
