If the activity in which you want to open the DialogFragment extends FragmentActivity, you should execute:

PicturePickerFragment dialog = new PicturePickerFragment();
dialog.show(getSupportFragmentManager(), "YourDialog");

Also you need to inflate your dialog layout file in the method onCreateDialog of your dialog fragment class.

Using AlertDialog.Builder you can achieve all this easily, e.g.

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

LayoutInflater inflater = getActivity().getLayoutInflater();

// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.dialoglayout, null))
 .setTitle(R.string.dialog_title)
 .setPositiveButton(R.string.pos_button, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // call the method on the parent activity when user click the positive button
    }
})
 .setNegativeButton(R.string.neg_button, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // call the method on the parent activity when user click the negative button
    }
});
return builder.create();
