Your website is made up of folders and pieces of artwork, beginning with your Home Page folder. Each folder can contain other folders or pieces of artwork, just like the folders and files on your computer. You should give each folder a name and a description to help visitors to your website understand how you have organized your work.
The organization of your website is entirely up to you. You might divide your work into categories based upon theme, medium or when you created the work. For example, your Home Page folder might contain folders called "Photography", "Illustration" and "Performance". The "Photography" folder could then contain folders called "Black & White" and "Color" - these folders would then contain specific pieces.
