several ways to to do this, for example

    public View getView(final int position, View convertView, ViewGroup parent) {

    ImageView myImageView = new ImageView(mContext);

            if (convertView != null)
                myImageView  = (ImageView) convertView;
            else
                myImageView  = new ImageView(mContext);

    Bitmap bitmapImage = BitmapFactory.decodeFile("/sdcard/myTempFolfer/" + myPics(position));
    BitmapDrawable drawableImage = new BitmapDrawable(bitmapImage );
