Javascript simple pop up on all site collection pages in MOSS 2007

Question

I would like to display popup for all site collection pages. Limitation is I am not allowed to touch master page. I do know we can do it with custom action in 2010 with scriptsrc attribute but it is not available in MOSS 2007.

Can anyone tell me how can I inject javascript on all pages without altering master page ?

Answer 1

Delegate control is alternative to master page / page layouts.

Answer 2

Edit all the page layout for each site to add the popup.
