iPhoto - Probably a massively noob question

Hello All,

In short I got my first Mac today after being a Windows user all this time. Everything is going well thus far bar one issue with iPhoto...

In short I transferred all of my photos from a USB drive into iPhoto, and now iPhoto is obsessed with trying to upload 10,000+ photos to photo stream!

I have checked and unchecked the option not to do this, but every time I re-enable it starts the huge upload again.

It seems to think because 10k photos were imported in the last 30 days, it must upload them and there is no obvious cancel button.

Can someone help or do I just have to wait 30 days and hope that it will stop?

Thanks

Ali

Thanks for replies so far, however I want to view my photo stream as it will contain photos from iPhone and iPad, I just don't want to upload from MacBook?

It would seem by enabling photo stream, iPhoto just has to upload any local photos added in the last 30 days?
