How to override a jscript include to get a different size popup?

For example, in the Advanced Search page, when you click on the help button, you get a popup window. Let's say I want to change the size of that window.

Searching around, I find that it is controlled by

/includes/templates/modules/pages/advanced_search/jscript_main.php

So rather than modify this file, I thought to create an override. But my approach doesn't work.

Would the path to my override be:

/includes/templates/modules/CUSTOM/pages/advanced_search/jscript_main.php

or

/includes/templates/modules/pages/CUSTOM/advanced_search/jscript_main.php

or

/includes/templates/modules/pages/advanced_search/CUSTOM/jscript_main.php?

I think I tried them all and nothing is working...

I'm afraid this is one that is not available for template override. You will have to modify the core file; keep a copy of the original somewhere safe, and keep a note to merge carefully when upgrading. You may want to keep a copy of your edited version elsewhere too.

Thanks for the reply.

BTW, a further thought.

Hard-coding the size of a popup window into each of these php files hardly seems like the most intelligent way to do it. This function could clearly have parameters passed to it (from a template that is actually capable of being overridden) that would specify the height and width of the window. Just a thought.
