How can I change the reference in Wikipedia’s “science fiction” hyperlink to a Google search for science fiction images.
I think we would need more context to understand what are asking.
On some Wikipedia pages you need the permission to edit it, and I don’t know all their rules, but I would imagine they may be more restrictive of who can make links.
Right, this is a site about how to do web development, not editing content on wikipedia. I’m sure you can find articles and videos explaining how to do what you ask.
