pDialog.setTitle("Sending Query");

nameValuePairs.add(new BasicNameValuePair("image2",image2));
if (Common.isInternetConnected(DetailsAcceptActivity.this)) {
try {
response = Common.httpPost(url_make_query, nameValuePairs, new String[] {});
// Jobj=jparser.makeHttpRequest(url_make_query, "POST", nameValuePairs);
Log.v(Common.TAG, "Record respose : " + response);
Intent intent = new Intent(DetailsAcceptActivity.this, LoginActivity.class);
DetailsAcceptActivity.this.finish();
startActivity(intent);
//Toast.makeText(MenuActivity.this,"Record Saved",Toast.LENGTH_SHORT).show();
/*JSONObject jObj = new JSONObject(response);
strRespCode = jObj.getString("success");
strRespMessage=jObj.getString("message");
int success=Jobj.getInt(TAG_SUCCESS);
if(success==1) {
Toast.makeText(MenuActivity.this,"inserted", Toast.LENGTH_SHORT).show();

return "NO_NETWORK";
}
return response;
};
protected void onPostExecute(String result) {
if (result != null) {
if(!result.equals("NO_NETWORK")) {
//groupMember.setSynced_with_server(StaticMembers.ONE);
}
//Log.w("strRespMessage= "+strRespMessage, "********");
// Toast.makeText(MenuActivity.this, "Query Sent!!", Toast.LENGTH_LONG).show();

pDialog.dismiss();
}
}.execute(null, null);
}
PHP Script to accept data from front end
<?php
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['sender_mobile_no'])) {
$name = $_POST['name'];
$image1= $_POST['image1'];
$image2= $_POST['image2'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
// connecting to db
$db = new DB_CONNECT();
$con = mysqli_connect(DB_SERVER, DB_USER, DB_PASSWORD, DB_DATABASE);
// mysql inserting a new row
$result = mysqli_query($con,"INSERT INTO tbl_query_master(name,image1,image2) VALUES('$name','$sender_name', '$image1', '$image2')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Order placed successfully.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>

You can encode your image bytes into String and then send it on server. You can use
String strImage=Base64.encodeToString(image1, Base64.DEFAULT); // image1 is your byte[]
and then set this String in your namevaluepair as
nameValuePairs.add(new BasicNameValuePair("image1",strImage));
In php:
you can decode your string to get bytearray as follows.
$str=$_POST['image1'];
$abc=base64_decode($str);
