HTML and CSS work! BUT...

So guess what! I can actually do this stuff. I was just making stuff up and it works! And with CSS I am actually starting to make things look cool.

And ive decided on an idea for my assignment. I wanna make a reference page/gallery of canberra's graffiti. This involves finding and taking pictures of the graffiti, as well as providing some insight into how and why people do it.

BUT. I have a problem. In playing with some design stuff I made a page which looked like a page out of a note book which had been drawn on. How ever images referenced in the CSS File dont load in Mozilla Firefox, and images in the code dont load in Internet Expoler...

Any Help?
