Automatic Alternative Text

Description

Automatic Alternative Text makes accessible images easy and fast by automatically generating alt text for images with Microsoft’s Cognitive Services Computer Vision API.

The Computer Vision API’s algorithms analyze the content found in an image and generates complete sentences of human readable language describing what is found in the image. The Automatic Alternative Text plugin gets this description and adds it as the alt text for each image uploaded while the plugin is active.

Why aren’t my images receiving alt text?

There’s several reasons an image might not get alt text:
1. Your API key is missing or incorrect. Make sure that your key is saved and accurate in Settings > Media. Also make sure that the key is for the Computer Vision API.
2. The service is not confident enough in the caption. By default the plugin will only use the received caption as alt text if the service is at least 15% confident in the result. You can adjust this confidence threshold in Settings > Media.
3. The service cannot connect to your server or is prevented from accessing the image for any reason. Try entering your image URL on this page to see if the service can connect outside the context of this plugin.
4. You’ve exceeded your key’s request quota. You can view your usage and upgrade your quota here.

Can I automatically add alt text to images I’ve already uploaded?

Not yet. I might add this functionality in a future version.

Reviews

Great plugin beyond of doubt

It’s a great plugin to increase images accessibility. But if i have already a website with ton images, it’s not so helpful for previous images. I’m really impressed.

BOOM. Great starting point for everyone everywhere.

I manage several dozen WordPress websites, and I have started installing these on every single one. Many of my clients have limited access to their websites, and are able to create new posts and pages. It can be difficult to keep up with the media that they are uploading to be sure that they include ALT attributes. This is going to be a huge time saver. No, it isn’t perfect, but that’s no fault of the plugin creator. This leverages the power of Microsoft’s Computer Vision API to generate ALT tags quickly for newly uploaded images. There isn’t an option to process existing images, and I do hope that it is included in future updates, but that’s no issue. I’m just happy to know that moving forward SOMETHING will be included for most uploads by default.

All of my websites are version 4.3 and up, and I haven’t had a single issue as of yet.
