hotspots

[linexpert]

hello,
i made a banner as an image. I'm putting hotspots on the parts of images to link them to other sites. Let's say i say link it to www.google.com it goes to http://mywebsite.com/site/www.google.com

how do i fix it and just make it go to www.google.com?

thanks
i'm using macromedia dreamwavers
