How to sync albums on my iPhone on to my computer?

I accidentally permanently deleted and misplaced all the folders of pictures I had on my laptop. I have a few folders on my iPhone from when I synced them on to my phone and I wanna know how I could place them on to my computer… It's just that those folders on my computer are deleted but they are on my iPhone still. I just want to transfer them on to my computer. I need help on how to do this because these pictures are VERY important to me. So if anyone knows how I could do this, any help will be greatly appreciated. Thank you.
