It seems like you're a novice to web-designing. The web librarian is anxiously waiting for you. LOL. Just teasing. Anyway, you'd need firsthand some knowledge of your program's setup, i.e. path to PhotoPost directory (/home/mydomain/public_html/photopost) , where to upload your HTML files to, etc.
1./ Use some HTML editor, i.e. NotePad, and create an HTML file called
HEADER.HTM. Below is a sample file.
Code:
Content visible to verified customers only.
2./ Upload the file to your PhotoPost directory.
3./ Login as admin user and select Edit Settings - Global options. Locate the section
Full path to Header Include file. To include an HTML file as the header, enter the full path., and enter the info, i.e. /home/mydomain/public_html/photopost/header.htm.
