Split the Slideshow region into two columns - new column to hold a new region

This is the way I did it:

1st: reduce the size of your sildeshow either by changing in style.css or over in local.css
}
.slideshow {
width:###px;
}

2nd:
add a new region by adding a new div into "slideshow-inner" div class and put it into the page.tpl.php in DL 7.XX.
set the required width and such, also use firebug or f12 in chrome to identify the css.

3rd:
add the new div class in style or local.css

4th: set your new content such as objects or pics in your page.tpl.php under the new class you just created

hope this does the trick.

I haven't found a easy way to do this.
if you do let me know
