            Bitmap bit = Bitmap.createScaledBitmap(S.Murge_Bitmap, 280,  280, false);
            public Bitmap[] mThum={bit,bit,bit,bit,bit,bit,bit,bit,bit,bit,bit,bit};
            public ImageAdapter(Context c) {

            return mThum[position];
            }
            public long getItemId(int position) {
            return 0;
            }


            public View getView(int position, View convertView, ViewGroup parent) {
            ImageView imageView;
            if (convertView == null) {   
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
            imageView.setScaleType(ImageView.ScaleType.CENTER);
            imageView.setPadding(1, 1, 1, 1);
            } else {
            imageView = (ImageView) convertView;
            }
            imageView.setImageBitmap(mThum[position]);
            return imageView;
            }

You can use this solution, but I think it's gonna give you only a Bitmap of displayed images :

Bitmap b = Bitmap.createBitmap(mGridView.getDrawingCache());

if you have an issue with this and can't get a bitmap, try this :

mGridView.setDrawingCacheEnabled(true); 
// Without it the view will have a dimension of 0,0 and the bitmap will be null          
mGridView.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), 
            MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
mGridView.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight()); 

mGridView.buildDrawingCache(true);
Bitmap b = Bitmap.createBitmap(mGridView.getDrawingCache());
mGridView.setDrawingCacheEnabled(false); // clear drawing cache

otherwise, if you want all your images from your "Adapter" you can construct you Bitmap like describe in this answer :

EDIT : I didn't see you wanted to save the image on SD card, there is plenty of answer about that so you should take a look at them :
