I can't receive picture messages on my Nokia N8?

I have a Nokia N8 and I'm on Orange network. My friend sent me a picture message from her iPhone but instead of me receiving the picture, I get a notification from Orange asking me to login to the Orange website to view the picture…

How come I can't view the picture under my messages in my mobile?

It could be the Orange site it's self, I'm with them and need to log on to get pics. I have a Samsung.
But see link and see if you can reset the phone, if unsure, don't unless you are capable.
Make sure you read all the info.first.

Nothing is wrong with your n8, its the network. Other networks do the same. Tell your friend to send the mms normally rather than go thru the networks system.

Hi.Call technical support & explain issue. Ask to do some trouble shooting steps
