IPhone 4 will sync on to iTunes but won't show up on My Computer?

I have the iphone 4, and when i attach it to my laptop itunes opens and syncs, which is good. But when i go to get my photos from my iphone it doesn't show up on My Computer on my laptop. I wanted to see if it would do that on another computer, so i used my dads and it worked fine and i could get my iphone photos on to the computer. But for some reason i can't transfer my iphone photos to my computer. Any advice? What can i do to fix this? Because i would like to make room in my phone and put the photos on my computer!
