I'm not exactly sure what your uploaded file does, but from the link it looks like a psd (photoshop) file. If you used photoshop to generate a website from images, no offense but I would recommend against doing so. While it is simple to create an image based website in photoshop and subsequently slice and upload it, the website will suffer.

In addition to slow load times because of being image based, text and graphics will rarely scale to a monitor resolution other than your own, consider widescreen monitors, 19 inch ones or 17 inch ones. Your website will display differently on different resolutions, rendering poorly at high/low resolutions. When designing websites, consider the speed at which your page loads an important factor. Try using CSS and xhtml to achieve both browser compatibility and stability over different resolutions, as well as quick load times. The average internet user expects pages to load in two or three seconds, and will move on if your website can't do this.

Ignore all of this if I'm wrong, again, I can't display your file in the link. If you were showing a screencap, perhaps .bmp or .jpg would be a better choice?

Also, its very possible you have the most amazing design that justifies the load times and I'm just biased towards minimalist, clean designs.
