How to get pictures off of iPhone onto PC?

Every time I plug my phone in iTunes just pops up, so any ideas how I can get pictures off my phone on to my laptop, i have windows 7 btw.

I use Dropbox--download the version onto your computer and phone and the two will sync. It's easy and awesome.

1. Connect phone to computer.
2. Ignore the iTunes pop up.
3. Click on "Start" button (bottom left on Windows desktop screen)
4. Click on "computer", iPhone should show up as "device with removable storage"
5. Open files, find photo's, cut and paste or copy into a new folder.
To create a new folder right click anywhere on your desktop screen, click new, name it, and away you go!
