Load Image Browser not in Root folder

I want to load up a folder by default, images in this case, but I want to have all the other folders one level up in the left column. So I have the files in images in the resources list and the folders images, gallery, flash, etc. on the left.

Here is my folder structure:
site
>
1
>
images
flash
template
gallery
etc.

Much thanks for your help! I hope this is not a stupid question!
