#### 34.2.3 Assigning WAI image attributes with PI markers

You can use PI markers to provide text equivalents of graphic images. The attribute value in the text of a marker applies to the next anchored frame in a flow after the PI marker. Each PI marker name must start with Graph and end with the name of the attribute. Valid PI marker names are as follows

GraphAlt | Short text equivalent of image; adds alt attribute.
GraphLongdesc | Path to file with image description; adds longdesc attribute.
GraphTitle | Long text description of image; adds title attribute.

For example, to provide an alt attribute for each graphic, place a GraphAlt PI marker just before the image.
