android - Picasso not loading the image

Question

here's the code for picasso:

ImageView img = (ImageView)findViewById(R.id.product_image);
    Picasso.with(this)
    .load(_url)
    .fit()
    .into(img, new Callback() {

        @Override
        public void onSuccess() {


        }

        @Override
        public void onError() {


        }
    });

here's the value of _url: http://kiagallery.ir/Images/Upload/Collection%20101/Spring%20101/d4a03b66dc7b46c694615c549b78b2e9.jpg

and here's the xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView 
    android:id="@+id/product_image"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<TextView 
    android:id="@+id/product_name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="13sp"
    android:layout_below="@id/product_image"/>

<TextView
    android:id="@+id/product_price"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="13sp"
    android:layout_below="@id/product_name"/>
</RelativeLayout>

as you can see the image can be accessed via browser but picasso fails to load it, I've checked the onError function and it's never called, I'm quiet lost here, any help would be appreciated.

EDIT: When I give imageview's width & height fixed value like 200dp, it loads the image, but when I change it to wrap_content it doesn't show the image.

Do not forget add permission to manifest

<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
