Un bon croquis vaut
mieux qu'un long discours. (A good sketch is better than a long speech.)
Figures and images
Images are placed in topic content using the image element. The image element can stand alone, or can be contained within a figure (fig) element.
Image file formats
Where there is no strong reason to choose another image file format, you should use SVG or PNG file formats in DITA topics.
Image alignment, placement, and sizing
The align, placement, width, and height attributes of the image element are used to specify the placement and size of images when generated to an output delivery format.
Images in titles
Images in topic, figure, and other titles, while technically valid, should not be used.
Callouts with keys, rather than text labels, should be used when identifying parts of an illustration.
Where possible, graphics that include text should be managed in SVG format to simplify localisation.
