Adding an image to a published app

[etrotter]

Hello Qlikers, 

My end users would like to use their own images in their storyboards in a published app.

Is it possible for end-users to add images to the media library in a published app? 

If there is no innate ability is there a work-around other than duplicating the app, adding the images and republishing? 

Thanks in advance for your help!
