I have downloaded and tried a few different background image plugins but I have the same problem with all. Basically whatever background image I upload (or simply change colour) the image overrides the content area too making the site illegible. I believe the problem might be that my site's template bkg is set to transparent but am not sure and am not confident enough to make code changes without knowing what to change.
Any help asap would be greatly appreciated. You can see the issue on ihcstudio.com
