How to remove a synced photo album from your iPhone 4?

So I synced a photo album to my iPhone 4 and now can't figure out how to remove it. I thought I had it figured it but yet it still is on my phone, taking up space.

What?

Firstly you will connect your phone to iTunes. In iTunes you can remove your photo album by removing the right symbol from photo function & then sync again. You can't delete the photo album by phone.
