SSL only partially encrypted after certificate renewal

Hello, I just renewed my SSL through Comodo and now I am getting the dreaded "page only partially encrypted" error. I was NOT having this error before and I have changed nothing in the files. I have been reading through other posts that have this issue, and don't see where my problem is. Below is the information that might be helpful. Again... I have changed nothing. I simply installed the new certificate and Comodo has verified that it is 'installed correctly'. I have been searching for hours and could really use some fresh eyes on this.
Thank you in advance.

• Site is set up to use a single directory for housing SSL and non-SSL content

• my config file in /includes:
  // Use secure webserver for checkout procedure?
  define('ENABLE_SSL', 'true');

// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
// these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');

• my config file in /admin/includes:
  define('HTTP_SERVER', 'http://www.photoimprints.com');
  define('HTTPS_SERVER', 'https://www.photoimprints.com');
  define('HTTP_CATALOG_SERVER', 'http://www.photoimprints.com');
  define('HTTPS_CATALOG_SERVER', 'https://www.photoimprints.com');

  // Use secure webserver for catalog module and/or admin areas?
  define('ENABLE_SSL_CATALOG', 'true');
  define('ENABLE_SSL_ADMIN', 'false');

// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
// these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
define('DIR_WS_ADMIN', '/myadmin/');
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_ADMIN', '/myadmin/');
define('DIR_WS_HTTPS_CATALOG', '/');

Another clue.. in IE, I let it display only the contents that were secure, to see what might NOT be secure. What didn't appear is the Comodo logo itself, the one in bottom right corner. Now I did not change anything with that logo. I figured it was the same logo as last year and didn't change any settings related to it. Should I have done something else?
Thank you

review the code for the comodo corner of trust logo. according to the dependencies on the page you are calling the corner of trust logo unsecure on secure pages

I'm sorry I don't have a clue what you just said. What do you mean, review the code?
Thanks,

This code at the bottom of your tpl_main_page.php file is wrong:

<script language="JavaScript" type="text/javascript">
COT("http://www.photoimprints.com/images/secure_site.gif", "SC2", "none");
</script>

you will notice it says http instead of https

I just installed a newer? Comodo trust seal contribution, and I think it is working. Would you be so kind as to hit the login button and see if you find that is the case?
Thank you,

yes, it is behaving correctly now.

Thanks, I had thought that since I already had a functioning SSL corner seal that I could just leave it alone when I installed the new certificate. I guess that's not the case! I don't understand the WHY of that, but I'm glad it's working and I hope I can remember that come renewal time next year.
