How to transfer a photo album from my iPhone onto my computer?

I have about 900 pictures on a photo album in my iPhone and i want to transfer them into my computer or even my camera roll that would be even better. How can i do that? I don't even have a option to save them

1. Hook up your charger with your computer there should be like a plug for it there
2. Connect your phone
3.It should show up how you want it to be viewed you should have test photos to see which one works better
4.It should give you a way to click the pictures you want which is the only way sadly
5.It will take time to upload if you have a slow laptop or computer avoid videos

Plug your phone into your PC via the USB cable. Go to My computer and double click on the iphone device it will open a folder called DCIM, your photos should be in there and can be copied to your pc from there
