this has two problems, first it wont let any other image selected as it requires second user will have to deselect and then only it can select new image and proceeded with it,
either this
new Gligar().requestCode(PICKER_REQUEST_CODE).withFragment(this).limit(1).show()
should allow selection of other images while one is selected or setSingleSelection(true) should be made that could introduce such behavior
