Logo Image at Top Left, change default link from board index

[PenelopeQ]

In Theme Options and Preferences I have an image in the space for logo image url.
This default links to the board index. I am running a Kickstarter campaign and would like to upload a different image during the campaign (easy) and have it link to the campaign. I  do not know how to change where this links--or if  I can change it. Can anyone offer me some directions to do this?

Make sure to back up your index.template.php first, just in case

Thanks.
I thought it might be a change like that rather than something more simple I could just do when I put the logo code into the box. I only want it there during the campaign and so I think changing the site slogan below is a better option--I just tried that and it's already working.
