Using Input File Upload within Phaser Canvas

[PapaPuck]

I'm creating a photo manipulation 'game' using Phaser.  The user needs to upload a file from their device (desktop, iOS, Android) to start.  Searching, I find examples where <input type="file" name="pic" accept="image/*"> transfers the image into the Phaser canvas.  And CanvasInput.js works if you only have a text field.  But is there any way to get file upload (and file save locally, for that matter) type input from within the Phaser canvas?  I want these input fields within the game canvas itself.
