Images from my stylesheet will not load

I currently using WAMP Server 2.1 on both my own computer and on my girlfriends 开发者_如何转开发laptop. I synchronizing my files through Dropbox and I link some images (the logotype, background-image, etc.) via my stylesheet to my personal website.

The images is visible on my own computer but they are just gone on my girlfriends laptop, just like as they are not on her computer which they are. All files are fully synchronized between these 2 computers and I ask you now; what do you think is wrong here?

WAMP Server has the same settings and modules on the laptop as on my computer.

Thanks in advance.
