A Header is the image that is typically found at the top of each page in your ePortfolio. In effect, it helps you visually brand your ePortfolio. Different themes call for headers of different sizes, and some themes even position the header in a sidebar. Matthew at Build Your Own Blog – Blogging Tips has a nice, brief video on adding a Header to your WordPress site.
Of course, you actually need an image to upload! You can easily grab a camera (cell phone cameras work just fine!) and take a picture for your header.
If you have image editing software and know a little about using it, you can even put text on your image. This gives you even greater control over your header font, enabling you to further customize your ePortfolio branding!
Our Images tutorial offers a basic introduction to image editing and suggests a few free tools you might use.
