Okay:

Good:

In the event that you should do therefore, explain exactly what your picture states inside your alt text.
Do not add « image of, » « picture of, » etc. in your alt text. It is currently thought your alt text is talking about an image, so there’s no want to specify it.
Don’t forget longdesc= » ». Explore making use of the longdesc= » » tag for lots more complex images that require a description that is longer.
