Returns the alt text for the image.
The value is based on the Alt-text field in the image settings.
(Page > Paragraph > Content tab > Image > Image Settings > Alt-text)
The alt attribute is meant to be used as an alternative text if the image is not available, not as a mouse-over text. To show a mouse-over text on images or image-maps, use the title attribute.
Example with alt text:
<img src="<!--@ParagraphImageClean-->" alt="<!--@ParagraphImageLinkAlt-->" />
Image titles can be set by the tag ParagraphImageText.
