I have created a website using Web Designer 11 Pro

It contains about 165 pages with text & pictures (in picture display Widgets)

Three seperate device types:
Main - 960PX
Mobile - 480PX
Notebook - 640PX

My index html page is very simple:
Several plain text boxes (5).
A single scrolling text box.
9 button Navigation Bar that links to 9 other pages that spiderweb out to various other pages.

My index.htm file is 5.26 MEGABYTES!!!!

Any reason why its so huge? (It takes FOREVER to load).

Hints for reducing its size to something more reasonable?
Do I have something turned on that I shouldn't have?

Thanks
Ron
