Captions

A caption to an image is a title, a label with several essential purposes. If all are fulfilled, specific formats are a matter of taste, but they should be fairly consistent within an article, for the reader's sake. Not every Wikipedia image needs a caption: some are simply decorative. A very few may genuinely be self-explanatory. If you decide that an image does not need a caption, then please follow the advice at Alternative text for images to specify appropriate "alt" text. Captions can be added by using the frame or thumb paramater as part of an image tag. For example: frame|Write the caption here.. Remember that some images, such as logos or element symbols, should not have captions.
