First you have to give an id to the tag then make an object to it and then you can change the source link for example if i have an id called "link" then
var changed = document.getElementById("link")
changed.src = "some_other_link"

Answer 9

Changing it by tag name

Then
var changed = document.getElementByTag("Tag")
changed.src = "some_other_link"
