Figures - Do you add useful and concise figure text?
When you add an image to a website or application, it is so useful to add a figure underneath it to describe your image.
It's the best way of ensuring you catch users' attention to the content of your page. When you're scanning a newspaper for interesting articles, you'll check out the pictures, read the accompanying description, and if it sounds interesting you'll go back and read the article.
Users read websites in a similar fashion. Catch their attention with an image, and then keep it with a useful description. Don't just describe what the image is; say what it's used for in the context of the document.
Tip: Prefix it with the actual word "Figure: ".
It is especially important that images and captions serve a purpose, as opposed to graphics which are there solely for design.
Tip #1 - Give bad and good examples
When possible, use "bad" and "good" examples to clearly explain Dos and don'ts. At SSW we always show the bad example first, then the good example. You will see samples of this in the next tips below.
Tip #2 - Bold your captions
Figure: Caption not bolded
Figure: Caption is bolded
Tip #3 - Describe the actions in your captions
Especially for screenshots, it is a good idea to have your figure describe the action the user would take:
Figure: This is the screen
Figure: Bad example - Vague caption description
Figure: On the screen, choose the execution method
Figure: Good example - Clear caption description
