Problem: In the development of SharePoint 2013 APP, we found an issue with upload a image from computer to a description field of a list in the app. Causes:  Whenever we are uploading a image to SharePoint list or page, the image actually stored in an asset library.But in the case of SharePoint app we don't find any such kind of library to store these files.Because of this reason, app wont find any place to store the image file then it will throw an error.​ Work Around : In order to resolve the above issue, we need to include a document library in the SharePoint APP.
