Copy photos from iPhone 4 to computer

Hi there,
I am trying to copy my photos taken with iPhone 4 to my computer.
I tried to sync it many times no use. All I learnt is u can copy photos from computer to iPhone not vice versa. Is that right?
If there is a way to copy photos from iPhone 4 to my computer pls lemme know.
Thanks for ur help.
Cheers

Plug in your phone, and start Windows Photo Gallery. Go to the File menu and choose import. Choose your iPhone and it will do the rest. They come up in your Pictures directory by default. Just to be clear, iTunes does not do this on Windows.

1.Connect the iPhone to your computer. Windows should automatically open the Scanner and Camera Wizard. Click Next.
2.Choose the photos you want to copy. Click Next.
3.Use the default picture name and destination, or change these as you wish.
4. Enable the option, "Delete pictures from my device after copying them".
5.Click Next. The Wizard imports your images.
6. Select what you want do with the images, or close the Wizard. Click Next.
7. The Wizard tells you the number of images that it imported, with a link to access those images. Click Finish to close the Wizard.

You can transfer them via iTunes directly.
