iphone photos do not show in photo stream

What happens if you save the attachment from your email to your "Downloads" folder, then drag it from Downloads into iPhoto?

That's not meant as a solution - more of a diagnostic to figure out what's going on.

OK - you have two separate problems.

1. Mail's "send to iPhoto" command is currently not working. It doesn't work for me either, though it did not long ago. So this is a new problem, you can use the "feedback" form to report it to Apple. Click the "Mail" menu in Mail, then choose "provide mail feedback" - it will also send Apple some information about your accounts, in case that's relevant.

2. Photostream. This is a completely separate problem, and you'll need to provide more details about what's happening. Take a look at a couple of things, and tell what you see:

• on the iPhone, snap a picture. Then go to the "Photos" app, and tap the "Photostream" (cloud) icon. Do you see the latest photo there?
• on the Mac, take a photo with photobooth then click the "share" ( box with arrow icon) and send the photo to iPhoto. Now go into iPhoto, and click the "photostream" icon in the left column. Is the new photo there?
• and the obvious questions (which I'm assuming the answer is "no" - but it doesn't hurt to ask again) - when you look on the phone in Photostream, do you see the picture you just took on the Mac, and on the Mac do you see the picture you just took on the phone?

Sounds like it's working then - probably something you did earlier fixed it, and you're just noticing the results now. If you want to, you can tap a photo that is missing from photostream, then tap the "share" icon and send it to photostream manually.

Also something to keep in mind - I think the photos don't get sent to photostream until you tap the "photos" app. I'm not 100% sure about that, but I do know that starting up the Photos app will cause pictures that you've taken in the last few minutes to immediately show up in photostream (assuming you have a wifi connection).

And your final question is completely off topic, but iChat has been renamed "Messages".

Thank you, you solved my issue too. Just to inform you the photostream does not import pictures unless you are in the photo app on your iOS device, 100% sure. That was my mistake, I didn't understand why it wouldn't load in my pictures, I was even watching the photostream in iPhoto and it never loaded! So thank you very much.

Photo Stream will automatically import photos taken by iPhone as long as PS is setup in both devices and in the iPhoto on your Mac has its preferences set this way:

and both devices are signed in to the same iCloud account.
