OK, Normally, when a image does not display in a browser, it means, the browser cannot find the path to that image. So, my first guess here would be that you did not define the correct path to those images.

An easy way to find the correct path to your image, is to go to the image itself, rightclick the name, go to properties, and copy the path. all you need now to do is to paste it in your code, including the name of the image.

Try this, and let us know.

try to resize the image. In photoshop, etc use "Save for Web" button to save your image to lower your image size. if the image size is bigger than it should be, background image cannot be seen in online web browser.

if the image size is bigger than it should be, background image cannot be seen in online web browser.

Now this is news to me. Can you elaborate some more on this? :-O

You need to encase the links in your css in quotes. For example, your #mainDiv is currently:

#mainDiv {
	width:975px;
	margin-left:auto;
	margin-right:auto;
	background:#FFF;
	background:url(images/main_bg.jpg);
	background-repeat:repeat-y;

}

When it should be:

#mainDiv {
	width: 975px;
	margin-left: auto;
	margin-right: auto;
	background: #FFF;
	background: url('images/main_bg.jpg');
	background-repeat: repeat-y;

}

I'm pretty sure the spaces I've put after each of the colons aren't needed but as you can see, it makes the syntax highlight better.

That isn't necessarily needed. Not all image editing software has a "Save for Web" option and Photoshop isn't free. The file size would just determine the loading time of the image. If you want to reduce the file size with minimal quality loss, I would recommend a free program called Riot (Radical Image Optimisation Tool). I use it at work and find it very useful.
