I created my wordpress website on the hosting companies sub domain, I then parked my own domain name on top of it.  I realized that I could type in my own domain name and it would load the website but when I went to another page, it would show the subdomain in the address bar.  I then went in to settings and kept the wordpress address the same as it was before with the subdomain but I changed the site address to my own domain name.  Did I change the right thing?  My goal is for the subdomain to never be shown in the address bar.  Once I switched that, all the pictures on my site were gone.  I then went through and updated the links to the pictures on my site to the new domain name.  The problem is that the theme I am using is not working correctly.  The logo and some of the websites design is no longer there.  How do I fix this?

Thanks,
