Just so we're on the same page, lets do this step by step and tell us if doing this still isn't showing you the option to sync photos onto your device. This is done without the sidebar showing, so click View (top of your screen) and Hide Sidebar if it is.
1. Lets start with a freshly opened iTunes. Click iTunes in the upper left, beside the apple, and click Quit iTunes at the bottom of the menu.
2. Plug in device.
3. Open itunes.
4. If it says "Library" in the upper right, click on it first.
5. Then click on your device (not the eject button pointing up, but on the device's name).
Are you saying you do not see Photos on the top of the bar on the screen that follows, after clicking your device?
