Upload image on mobile app

Hi,   Currently we are working on a application where we take a picture in the mobile application and send it to the desktop application, but right now its only possible to take a picture while being in the app.   Is there also a way/widget to upload a picture from your phone gallery instead of having to take the picture while being inside the app? Thanks in advance!
