Answer: Both. The image of the chair is not essential to the information on the page. However, Guideline A tells us that all non-text elements must have an ALT attribute even if that attribute's value is empty.
How can we represent the following information in a different format that does not rely on color?
Items listed in green are required.
Required
Backpack
Socks
Toothbrush
Map
Not-Required
Lantern
Rope
Thermal underwear
Anti-venom kit
Fire extinguisher
Bug Spray
Guideline F: Client-Side Image Maps
Image maps provide a means to make parts of an image "click-able". User's of screen readers would have a difficult time navigating the image map without some additional information.

Answer: I don't know. But the KISS method tells us that we should not include these types of images unless we want to invest the time into researching the exact refresh times in order to be sure that the images are compliant. Besides, most animated images only detract and distract from the true importance of a web page.
Guideline M: Applets and Plug-Ins
In order to make our page(s) more accessible, we want to provide all the necessary tools to view our page(s). If these tools include programs above and beyond the web browser, then we must provide a link to download the tool.

Labels are necessary to identify what information is to be provided for each form field. Here the text in the left column acts as a label to the form fields in the right column to a visual web user. However, screen readers have a difficult time associating the label with the form field without extra assistance.

Consistent pages may have navigation links on every page. A screen reader must read through the navigation links every time a page in the site is loaded. This can become monotonous and time consuming especially if the navigation link list is lengthy.
