Share image in windows phone

问题

I am using v7.1 sdk for developing windows phone 8 application ( as my system doesn't support windows 8 so i cant use window phone 8 sdk). I want to share image . In windows phone 8 sdk it is possible using SHAREMEDIATASK but in windows phone sdk v7.1 it is not possible . Now the only solution is to save that image in library and open programmatically, i am doing it like this :

MediaLibrary library = new MediaLibrary(); 
WriteableBitmap wbmp = new WriteableBitmap(canvas1, null);
MemoryStream ms = new MemoryStream();
System.Windows.Media.Imaging.Extensions.SaveJpeg(wbmp, ms, wbmp.PixelWidth, wbmp.PixelHeight, 0, 100);
ms.Seek(0, SeekOrigin.Begin);
library.SavePicture(string.Format("Images\\{0}.jpg", 0), ms);

At this point image has been saved , now how to open it progarmmatically ?
