Ok instead of these parts:
ImageToolbar fill Vtec Topbar-16by12.jpg
ImageSwitchbar fill Vtec Sidebar-16by12.jpg
ImageMirc Center Vtec Logo.jpg
ImageStatus Center Vtec Logo.jpg
Imagechan Center Vtec Logo.jpg
Imagequery Center Vtec Logo.jpg
Imagebuttons Buttons.PNG
You have to use something like this:
ImageToolbar !Script theme.imagetoolbar
ImageSwitchbar !Script theme.imageswitchbar
Then in your [mts] section you need to type this:
Script <file.mrc>
<file.mrc> should be a script file in the same directory as the theme.mts file and it should contain the aliases you specified above in the ImageToolbar and ImageSwitchbar sections. These aliases are responsible for choosing and displaying the images.
