Problem with syncing iPhone with iTunes?

I have an iPhone 5 and I haven't updated to iOS 7 and I don't plan to. However, I have the latest version of iTunes (my brother updated it for me without letting me know).

Now, whenever I plug my phone into my laptop, iTunes never opens automatically anymore. But that's not the problem. The problem is that I can't sync my phone with iTunes. My computer knows that my phone is plugged in so I can still access photos/videos through here: image

But iTunes doesn't know that my phone is plugged in. It would usually sync automatically but now it doesn't do that and I can't even sync it manually either. This is what appears: image

It's really annoying me that I can't add any music or videos onto my phone. My USB cable is perfectly fine and both my iPhone 5 and laptop are still pretty new.

I uninstalled iTunes and re-installed it but that didn't do sht.

I'm worried that I'll have to update to iOS 7. But what if I do update and it still doesn't sync… I'll be even more annoyed because I really do not want iOS 7.

How to save lots of pictures from dropbox?

I have around 300 pictures sitting in my email my friend sent me, but she had to use dropbox to send so many in one email. I don't have the patience to sit there and click on each individual link to be re-directed to a webpage where i have to screenshot the photos with my iphone just to save them. Is there ANY way i can save them all at once without having to click each individual link?

Added (1). I'm already a member of dropbox, yet it is not an option i can see in my email.

Added (2). I went on her computer and used my own email, to clarify. So it was used with my dropbox, but on a different computer

Iphone over capacity because of Documents and Data?

Yep every once in a while I get to where I would just love to throw my iphone off of a cliff.

So I synced my phone and at the bottom of iTunes on the bar it says not only that my phone is 375.6 MB but that a HUGE chunk of that is "documents and data", 9.84 GB of it.

My questions are: 1. What in the f___ is that? & 2. How do I remove it?
