Access photo gallery to upload photos by inappbrowser

Personal I have a news app, I have partnered with a classifieds site and I put a button in the app that directs the classifieds using the inappbrowser, however when the user of the app is inside the site more precisely on the tab to put a product, it needs to post a photo of the product, the problem that when the user clicks the image button nothing happens, does not open the window to choose the photo ... testing with the native android browser without using the app, it works normally the image button of the site until the option to take photo, already using the app, nothing happens ... I believe it is permission but I do not know how to solve ... I am using dreanweaver to write the codes (jquery-mobile ) and then compile with the phonegap build CLI 6.3.0, I use the plugin inappbrowser to navigate the site and whitelist plugin to release the Http accesses. Someone can give me a light ... thank you in advance.
