5 column liquid header, can't make it work

[djvk87]

I am trying to design an image header for my website and I have split up an image into 5 pieces. I wish to make them as follows (in order)...
Left image, repeatable image 1, center image, repeatable image 2, right image.
I need the left, center and right images to remain fixed size and position but I need the repeatable images to fill in the space when the windows size changes.
I have made 5 divs within 1 container div all with their own css styling and tried to make this work but have had no luck. Can anyone point me in the right direction?

Thanks

#container {
margin: 0 auto;
width: 612px;
}"
