Hello, I am wondering how to add Alt text, or image descriptions to pictures on a website. For clarity, this is not my own website, but a website for an organization that I will be volunteering at. The website is fully accessible with VoiceOver. The only issue is that the website has a lot of photos, and it does not have image descriptions. I would greatly appreciate it if someone could walk me through the steps on how to add Alt text to images on websites that are not personally owned.
