innaccuracy: "Quick Tip: Using alt Text Properly"

[brucelawson]

Not so much innaccuracy as requiring some more information.

• "not necessary for understanding the content of the page (alt=”“).", I'd also note: "If, for example, the information in a graph is explained in text below it, there's no need to duplicate that in alt text"
• I'd add "images that are links should describe where they go. For example, a logo that is a link to your home page should have alt="homepage".
• I'd also add "Alt text describes the function of an image,and is rarely a detailed description of the image itself"
• I'd also add "Never begin alt text with "photo of.." or "picture of.."; assistive technologies already do this. Redundancy and repetition is almost as bad as not enough information.,

(Is the article on github for me to amend a send a pull request?)
