Photos won't send through Micorsoft Mail

When I'm in my Hotmail, I can attach a picture to an email and send it fine. When I go to that picture on my computer and try to send it through Windows Mail, by choosing: 'Send to', 'Mail Recipient', 'Attach', choosing the address and then sending, I get an error message. The message is as follows: "The host 'Telus' could not be found. Please verify that you have entered the server name correctly. "

I know I previously, at some point, entered Telus (my internet service provider) as both the account and server. (Maybe when I set up my windows live mail?) This is not correct. How do I correct things so I can send pictures through Windows Mail?

 

Problem solved!

Thank you Steve. That solved my problem! I don't know what it said before. I don't think I had a default program listed. However, I now have my default program as Windows Live Mail and it works!! As a bonus, I didn't even know there was a Tools button on Internet Explorer. I had repeatedly been changing my default browser through Tools button inside Windows Live Mail and it wasn't working.
