Probably however I’m not familiar with your specific theme.

These tools essentially convert the ascii characters:
< and >
into their html entity values:
&lt; and &gt;

WordPress is trying to interpret the code I will be looking into how to stop this from hapenning in the future so that code can be posted in replies. However for now go back to your header file and replace the line of code that says:

<br><br><br><center><?php show_media_header(); ?></center><br>

with:

<br><br><br><?php show_media_header(); ?><br>

This will basically remove the code that makes it align to the center of your page. It shoudl now align to the left of the page. However this might not be exactly where you want it to be. You will see what I mean after you do that. What you will need to do in the end is re-create the logo on the background you want with a large background to the left of it that will essentially push it out to the right the correct ammount. (I can try to explain this in more detail later if you are the one creating the actual logo.)

If you don’t want it on all pages then only select it form the second drop down in the Headers > Setting option in WordPress. You woudl then need to figure out how to manually set a different one of the rest of the pages.

#2 I have entered the line of code into the header.php file, under header see below. I am a little confused because in your directions you say to enter the code

and now you are asking if I entered it under the tag? Below is what it looks like right now.

I deleted the code because it does not help.
There are two things I would like you to check:

1. Have you selected your image: “AE Logo.png” in both drop downs inside of WordPress under: Headers > Settings ? (Tip: whenever naming something for the web try to not have any spaces in the name)
2. Have you entered the line of code from the post in your Header file under the tag ?

I reactivated the plugin, uploaded the image, changed the default settings and even deleted the old image so that I could tell each page which image to use. So it lets me select the image, write now I am only working on one page, the furniture design page. If you went to my website you would have seen a blank square where the image goes. If you click on the furniture design page you will see the image I want to use on that page centered in the header area.

It looks like you might not have read my article above. Have you installed the plug-in and edited the code specified in the header.php per the instructions above ?
