ALT text instead. For the latter, the image is exported as follows:

text.
OR

Back, Forward, etc.), text on the image is automatically taken,
exported as ALT text (i.e., Back, Forward) and presented to a screen
reader. If a title graphic is specified, the title text is used as the ALT
text.

Applying image adjustments
The Picture context toolbar appears automatically when you select an image
on the page. You can use the toolbar to improve the appearance of any image
appearing in your drawing by adjusting brightness and contrast directly,
setting levels and contrast automatically, fixing red eye or by applying Image
adjustments. The context toolbar also hosts other photo manipulation tools.
Image adjustments are made possible with a comprehensive mix of colour
correction/adjustment tools for use on your newly imported images. Levels,
Colour Balance, Channel mixer, Dust and Scratch Remover and
Hue/Saturation/Lightness corrective adjustments, amongst others, are
available. Effect-inducing adjustments also range from the artistic Diffuse
Glow to various blur effects. In fact, over 20 adjustments can be directly
applied to your image not only individually but cumulatively.
Adjustments are managed in the Image Adjustments dialog. The gallery
offers a one-stop shop for applying your adjustments—all supported by a
dynamic preview window!
