You'll want to go to http://www.trustlogo.com/trustlogo_choice.html in order to grab the image. It will give you some choices.

Once you've chosen which image to post to your site, you'll download that image file. Then, in your site admin panel, you'll go to Cart Settings -> File Manager.

Launch the File Manager.

From here, you'll be able to browse
files on your PC and grab the TrustLogo you chose for upload as shown below.

It is best to upload the image to the [cart root]/images folder if it is uploaded anywhere else you will need to go to Cart Settings -> Search Engine Settings and regenerate the .htaccess file or else the image will not be visible to the public. Once the file is uploaded, you'll want to return to http://www.trustlogo.com/trustlogo_choice.html and "Click here to install Corner of Trust Logo" or "Click Here to install standard TrustLogo" at the bottom, depending on your preference.

Part B:
The most preferred method of displaying a trust logo is to display it on every page. To do this, you will want to put the code from Step 1 on Comodo's site logo into the file:
/content/skins/_custom/skin/templates/wrappers/elements/element-custom-head.html
**Note: if you do not see the file or folders listed above in /content/skins/_custom, please follow the instructions in Part D below.
You
can use either the cart’s file manager or FTP to edit
element-custom-head.html and add the ssl logo code. Once adding the
code you will have to launch design mode and then exit to recompile the
cart's cache folder. To activate Design Mode, go to Cart Settings -> Appearance Settings, then click Activate Design Mode. If
you want the logo only on certain pages, you can use design mode to
navigate to the appropriate pages, and then right click on the body of
that page and edit the element source. You can then paste in your script
for the logo and save your changes.
Part C:
The code from Step 2 on Comodo's site can be added directly to the end of the footer.html area in the Cart Designer. This can be done by activating the Cart Designer, scrolling all the way down, right-clicking in the footer area and choosing 'Edit Source Code'. It should look like this:

Part D:
You
will need to create a blank html file named element-custom-head.html
using an appropriate program. Then, upload it into
/content/skins/_custom/skin/templates/wrappers/elements/. If one or
more of these folders do not exist, you will need to create them. Keep
in mind that you can create both the html file and folders using Plesk,
if available. Once this file is saved, you can follow the instructions in Part B.
