WHy haven't my photos shown up on Photostream.

I've taken 18 photos today ( this morning ) in the park. I then went home to my place where I have my WiFi network.

Only the first six of the photos appeared on Photostream.

Any ideas why they all didn't upload...and how can I fix this?

Thanks

So it now the 7 am the next day. I've taken x 2 photos this morning, and they haven't loaded to Photostream. However, another 5 photos ( out of 18 ) from yesterday morning have just shown up ( so thats approx a 24 hour delay ).

Am I right to assume then there's something wrong with the Apple servers?
