Knowing what to use for each can be frustrating, however, so some basic guidelines follow, plus Examples and a note about Usage Rights.
In our CMS, the title is sometimes visible (Gallery Images) and other times not (Slideshow Images). In either case, however, titles should be kept as brief as possible.
Captions should not be literal descriptions of the image. Instead, they should connect the image to the page or site it resides on, by providing context to the site's goals, events or other desired information. A key exception to this is in instances where specific descriptions may enhance the message.
Captions are not always available (Gallery Images), but areas for description are present and can serve much the same purpose.
The Alternate Text (or 'alt text') attribute is used by screen readers, search engines and when the image cannot be loaded. Alt text is intended to represent the image for non-visual situations, so it should be a literal (but brief) description of the image.
The alt text attribute is sometimes only visible AFTER a file has been uploaded.
