Can't Link Images To Content

Hi,

I’m trying to make a image clickable so once clicked it downloads content from my hosting. I have linked the image to a zip file thats on my hosting, But when i save the page and click on the link it adds this URL in front of it automatically: http://www.marketing-blueprint.co.uk/listb

So my URL looks like this: http://www.marketing-blueprint.co.uk/listbwww.marketing-blueprint.co.uk/SCFD.zip

I would like to remove the http://www.marketing-blueprint.co.uk/listb.

All other images that are linked are working fine. Just can’t get this one to work.

Hope someone can help!

Thanks,
Akeel
