Create alt text for images

Description

Description Ask Copilot to write alt (alternative) text for images so that people who use screen readers will know what the image portrays.

Why? Writing good alt text can be time-consuming, especially for more complicated images. While the alt text that Copilot produces normally needs some tidying up, it’s often quicker than starting from scratch.

Instructions

Step 1: Find an image that you want to add alt text to.

Step 2: Go to Copilot (office.com/chat) and sign in with your Coventry account. If you’re already using Copilot, just select the ‘New chat’ button at the top right.

Step 3: Copy and paste the following prompt into Copilot, then use the ‘Add a file’ button (the paperclip 📎 icon) to attach your image. When you’re ready, select the ‘Submit’ button (the arrow at the bottom-right):

🤖 Prompt (click to expand, then copy and paste into Copilot)

Here’s an image. Firstly, I want you to tell me what the image is.

Secondly, I want you to ask me where the image will be used, and what the purpose of the image is. Wait for my response. Then create appropriate alt-text for the image.

The alt-text will be as an accessibility feature to explain the image to those with visual impairments or similar. Please avoid using specific colours in your description.

Step 4: Check the alt-text that Copilot produces. Would it adequately describe the image to someone who can’t see it? Think about the function the image serves in its context. Ask Copilot to make tweaks if necessary (or you can manually make these yourself).

Step 5: Copy and paste the alt text into the alt text box for the image. For example, in PowerPoint you can see the alt text box by right-clicking on an image and choosing ‘Alt Text’. In Aula, in edit mode, click on an image and then choose the icon for ‘Edit alt text’ (it looks like a document). Make any changes as necessary.

Important: Always check Copilot’s output. Generative AI tools can hallucinate (create plausible but incorrect information).
