Windows Phone not getting tile notification with remote internet image uri.

Hi,

  I have implement the tile Notification with remote internet image uri in windows phone. At the time of binding the tile notification with channel uri  with image base domain uri(https://plashdevstorage.blob.core.windows.net/), but when i am sending the tile notification from server with image path in background image. the tile notification is not getting in device.

Template

<?xml version='1.0' encoding='utf-8'?>
<wp:Notification xmlns:wp='WPNotification'>
 <wp:Tile>
<wp:BackgroundImage>https://plashdevstorage.blob.core.windows.net/boldsky/1188_259_Image1_22-sinus-problem.jpg</wp:BackgroundImage>
<wp:Count Action='Clear'>2</wp:Count>          
<wp:Title>Notification Hub11</wp:Title>
 <wp:BackBackgroundImage></wp:BackBackgroundImage>
<wp:BackTitle></wp:BackTitle>
<wp:BackContent>Test message10</wp:BackContent>
</wp:Tile>
</wp:Notification>

Again When i am sending the Tile Notification with image path (not included base domain path in image url) from server , the notification is getting in device without background image.

template:

<?xml version='1.0' encoding='utf-8'?>
<wp:Notification xmlns:wp='WPNotification'>
 <wp:Tile>
<wp:BackgroundImage>boldsky/1188_259_Image1_22-sinus-problem.jpg</wp:BackgroundImage>
<wp:Count Action='Clear'>2</wp:Count>          
<wp:Title>Notification Hub11</wp:Title>
 <wp:BackBackgroundImage></wp:BackBackgroundImage>
<wp:BackTitle></wp:BackTitle>
<wp:BackContent>Test message10</wp:BackContent>
</wp:Tile>
</wp:Notification>
