Individual variables for submenus

Hi all! I’m new to the forum and also new to web design…so bare with me here.
I have a javascript menu on my site that has up to 3 submenus(1_1_1_1=four total menus). The last of these menus displays an image (image of artwork). I would like for this image to allways appear in a fixed location, relative to the window, which is below the first level menus that are displayed horizontally accross my screen–as opposed to always displaying relative to its parent submenu.
My site is
There you can see what it looks like.
The first level menu would be Portfolio, Media, Essays, etc…
The second level under Portfolio is Painting, Installation, etc…
In the third level menu whos parent is Painting, I have too many menu options and it often runs too far down…which makes it problematic if you have a small monitor like me.
*In an ideal setting, I would either have a scrollbar on the child menu of painting (third level menu), or make the text and space alloted a bit smaller–while leaving the rest of the menus as they are.
*Furthermore, the forth level menus, which would show the images of the paintings would always appear in a fixed position in relationship to the whole page, while alowing the rest of the menus to be relative.
I hope this post is not too long and/or confusing. Below is the javascript text I’m using to configure the menu.
I look forward to any advice.
