How do I stop iTunes from automatically backing up the iPad?

I'm trying to move some pictures from my laptop to my iPad, but every time the first thing iTunes starts doing is making a backup of the iPad.

But since I already keep a backup at my desktop, I want iTunes to back off and just let me move the pictures!

So how can I prevent iTunes from making automatic backups?

I'm using Windows 7. But feel free to leave OS X solutions as well.

Solution 1:

Mac Answer:

You can disable device backups with this terminal command:

defaults write com.apple.iTunes DeviceBackupsDisabled -bool true

Solution 2:

Go to iTunes and open its Preferences window (Command ⌘+,). Select Devices from the toolbar and check the "Prevent iPads, iPods from syncing automatically" option.
