Alt Text for School Newsletter Images: A Practical Writing Guide

Every image in a school newsletter should have alt text. This is not a suggestion for technically advanced school communicators. It is a basic practice that affects whether a significant portion of your families can access the content you are sharing. Screen reader users hear alt text. Families with images disabled see alt text. Families on slow connections who did not load the image see alt text. When alt text is missing or generic, all of these families get nothing, which means the information you communicated visually is invisible to them.

Who Relies on Alt Text

Alt text serves more people than most school communicators realize. Families with visual impairments who use screen readers is the most commonly cited group, and they are real: the CDC estimates that about 12 million Americans over 40 have vision problems that affect reading. But alt text also serves families who have their email client set to block images by default, which is the default setting in many corporate and government email systems. It serves families in areas with unreliable internet connections where images fail to load. It serves parents who are using email on a phone in a context where they have disabled image loading to save data. For any of these readers, alt text is what they see instead of the image.

Writing Alt Text That Actually Communicates

Good alt text conveys the same information a sighted reader gets from the image. For a photo of students presenting at the science fair, a sighted reader sees the activity, the context, and the people involved. The alt text should convey the same: "Eighth grade students presenting chemistry experiments at Lincoln Middle School Science Fair." For a photo of the principal standing with award recipients, the context matters: "Principal Rodriguez with four students who received the Lincoln Excellence Award in the school gym." The person reading the alt text should get enough information to understand what the image shows and why it is in the newsletter, not just that an image exists.

What Not to Write as Alt Text

Several alt text patterns are common and genuinely unhelpful. "Image" or "photo" tells the reader nothing about what the image shows. File names like "IMG_4829.jpg" or "DSC_2034.png" are auto-populated in many upload tools and convey nothing useful. "School photo" is only marginally better. These are the equivalent of having a sighted reader look at a photo and being told only that they are looking at a photo. The caption-as-alt-text mistake is also common: reproducing the image caption verbatim as alt text means the same text gets read twice for screen reader users, which is disorienting. Alt text should describe the visual content of the image. Captions can provide additional context, but they are not substitutes for each other.

Decorative Images and Empty Alt Text

Not every image in a school newsletter needs a description. Purely decorative elements, divider graphics, background patterns, and ornamental icons that add visual structure but carry no informational content should have empty alt text rather than skipped alt text. In HTML terms, this means alt="" rather than omitting the alt attribute. When the alt attribute is present but empty, screen readers know to skip the image silently. When the alt attribute is omitted entirely, some screen readers announce the file name, which is even more disruptive. The rule is simple: if the image conveys information, describe it. If it is purely decorative, use alt="".

Building the Alt Text Habit

Alt text is most reliably written at the moment you add an image to the newsletter, not as a retroactive review step. When you insert an image into your Daystage newsletter and the platform presents an alt text field, fill it in before moving to the next element. If you wait until the newsletter is complete to go back and add alt text to every image, it becomes a chore that is easy to deprioritize when you are running short on time. A brief description written in the moment when you just added the image and know exactly what it shows takes about fifteen seconds. It is genuinely one of the highest-impact-to-time-required accessibility practices in newsletter production.
