Is aria-label the correct attribute to use?

[jeremiak]

The component currently takes the alt text from the children images and adds them to the <div> with an aria-label attribute, but should it instead be aria-description or aria-describedby?

From the MDN docs:

The aria-description attribute is similar to aria-label in that both provide a text string to associate with the element, but a label should be short and concise, while the description can be longer as it is intended to provide more context and information.
