I've not used this theme setup, but based on the code you showed,
Code:
ImageToolbar !Script blue.top

ImageSwitchbar !Script blue.side


I'm guessing that the !Script notes that you want the aliases above to use the other aliases.

If you look at the code of one of the above aliases (ImageToolbar, ImageSwitchbar), for the !Script word, you can probably determine what it is wanting to do. If not, feel free to post the code of one of the aliases so that we can try to figure it out.
