You need to edit the html template file to correctly point to the css and image files for your site.

So, if you've got the template in the directory: templates > templatename

You would have to edit the .html file so that images point to:

templates/templatename/image.jpg

And the css path would be:
templates/templatename/style.css

Also, you may have to change some file paths inside the .css file, but usually this isn't necessary. Hopefully you know what I mean, if not please let me know and I'll try and explain better.
