Go to google.ca or a search engine and type in imageshack. Click on the first website on the top that appears. Then it will go to a website that lets you type in a URL or insert a file. Then insert the banner you saved and then it will create a link for it. Then copy the link and go to edit signature on your MMA profile. Insert the link and then it will appear your banner in your signature. I hope you understand. If not reply in this thread of post your banner here such as attachment and I will give you the link to it.
