Header image does not display on log in page

I have Zen Cart 1.3.7 installed on my site and when customers visit the store my header displays fine. When they click on the log-in hyperlink to log in the header no longer displays properly. When I click on the image properities, zen cart appears to be looking for the following:

http://www.desertdogsmusic.com/store/includes/templates/Desert_Dogs/images/logo.gif

I know that this path is correct and that there is a logo.gif file located there. The only difference is when you click "log in" you are taken to a secure portion of the site, so Zen Cart looks for the image header here instead:

https://www.desertdogsmusic.com/store/includes/templates/Desert_Dogs/images/logo.gif

Here is a link to my store so you can see what I mean:

www.desertdogsmusic.com/store

When you get there, click on the log in link in the upper left corner to get to the customer log in page. As soon as you do, the "keyboard" image in the header no longer loads. What could I be missing? Is there a file that I need to edit? Or is there a bug in 1.3.7?

Thanks

More Information -

I also noticed that the log in button does not display either.

With a little further research, I discovered that there is a problem with the SSL certificate on my site.

Any suggestions?

Thanks

looks like you got it fixed. Please let others know what you did

THIS PROBLEM HAS BEEN FIXED...

I contacted my hosting company and tech support had discovered that there was a problem in the .htaccess file. A single line was preventing the loading of images on a secure server, once that line was remarked out, the images will load properly.

If you are having this same issue, have your hosting company check out your .htaccess files.

Thank you
