how to get all images and photos from my android device not from sdcard?

i would like to get all images/photos/wallpapers from my android device with image saved path.

I have implemented code for collect the images from sdcard as follows:

String[] mProjection = {
    MediaStore.Images.Media._ID,
    MediaStore.Images.Media.DATA
};

mCursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
    mProjection,
    null,
    null,
    MediaStore.Images.Media.DEFAULT_SORT_ORDER);

from the above code i can able to retrive the images from sdcard only.But if the images are available in device phone memory then how can i retrive the images/photos/wallpapers? If i use INTERNAL_CONTENT_URI it is not returning wallapers info other images information

please any body help me....
