Saving Images using Windows 7 and Windows Live

I am using Windows 7 on my computer and I am also using Windows Live for email. Recently I have received four mails with one image attached from my friend. But the problem is when I am trying to save the attachment it asks for the location for saving, but the file type shown is only ‘.att’. Also when I save through the File menu via Save attachment option it saves the text and image, but the name of the image file cannot be changed, all attachment files are named as ‘photo.jpg’. So each time I save files, the previous one saved is overwritten. Any ideas?
