Let's take a closer look at the New Photo page, particularly the Photo Content form:

For now, we'll concern ourselves only with the basics of composing accompanying text for a photo:

Photo Caption
A photo's caption is analogous to an article's title. The caption can be up to 254 characters long.


Photo Description
A photo's description is analogous to an article's body. Enter the description of your photo into the Photo Description Editor. The description can consist of virtually any length of text and can contain just about anything that can be put into a web page (including text, links, images and so on). For now, we'll enter only text.

As with the body of an article, you enter the description into a special text field called the Article Text Editor, which has features that offers "What You See Is What You Get" or "WYSIWYG"-style editing, just like a word processor.
