All of my computer image files have gone onto my iphone?

All off my computer images have synced to my iphone and I can't delete them on my iphone? They are all set in albums on my phone the same on my computer and I just want to delete the albums. How do I delete them through ITunes or my computer please? I have the new IOS 7 software on my iphone to just in case that effects anything.

It could be to do with your settings on iTunes. When you connect your phone there should be an option at the top for photos. Click on it and it might have the option to sync all photos from your computer selected. Try changing these options and syncing again to see if they go.

Hope this helps
