right, im working them right now. i changed my names and everything.
so all my pages should look like this (my_page.html)
and my pictures and logo's should be like this right? ( my_pic_.jpeg)
like spaces are replaced with underscores and no caps in the names?
That would definitely cause an issue, your browser won't know what to do with a .htl file stick with .html, .htm, or .php if you're using php in your site.
