I am not sure why you are using pdftooltip here when you can just add the alternative text to the call to includegraphics. Also, the seal is an artifact rather than an actual figure in my opinion and you can tag it as such so that no alternative text is needed. From W3 artifacts are "generally graphics objects or other markings that are not part of the authored content. Examples of artifacts include page header or footer information, lines or other graphics separating sections of the page, or decorative images."

Hi Kelli- thanks for your review. My responses:

• This mistake was because I'm so new to LaTeX and was trying to implement a solution I saw on StackOverflow. Thanks for sharing the better way to do that.

• Thanks for letting me know. I agree that the seal is, in fact, in artifact. My next commit will include the .tex file with the alt text removed and the artifact tag added.
