# Webflow CMS

> Add alt text to Webflow CMS collection images, which the app can't reach, using the AltTextLab browser extension.

Because of Webflow platform restrictions, the app works with images on the page canvas and in the Assets library. It can't read or update images in CMS collections, including CMS image fields, gallery fields, rich text images, and alt text stored on CMS items.

## What the app covers

| Content | Supported |
| - | - |
| Static page images | Yes |
| Assets library | Yes |
| CMS collection images | No |
| CMS rich text images | No |

## Workaround: browser extension

Use the AltTextLab browser extension to generate alt text for CMS images, then paste it into the CMS item.

**1. Find the image in your CMS**

In Webflow, open the CMS collection item and find the image field and its alt text field.

**2. Generate alt text**

Right-click the image in the CMS item and select **AltTextLab: Get alt text**.

**3. Copy the result**

Copy the text from the popup.

**4. Paste it into the CMS item**

Paste the text into the image's alt text field in the same CMS item. Then save the item.

The extension lets you set the language and writing style. See the [browser extension overview](https://www.alttextlab.com/docs/integrations/browser/overview), or install it for [Chrome](https://www.alttextlab.com/docs/integrations/browser/chrome.md), [Firefox](https://www.alttextlab.com/docs/integrations/browser/firefox.md), or [Edge](https://www.alttextlab.com/docs/integrations/browser/edge.md).

## Other options

These are alternatives, not replacements for the app:

* **[Web snippet](https://www.alttextlab.com/docs/web-snippet/index.md)** — a script that adds missing alt text on your live site automatically, including images that come from the CMS. 
* **[API](https://www.alttextlab.com/docs/api/index.md)** — for bulk workflows you build yourself.
