Images Intelligent Guided Test
The images IGT walks you through the accessibility testing of your images.
The Images IGT does not currently cover font icons (like Font Awesome).
How it works
Step 1: Selection
The images are grouped using an algorithm to categorize similar images. You can select the images you'd like to test. Once you have selected the images you wish to test, click "NEXT".
Step 2: Purpose
From the images you have selected to test, you will be asked to select all images that are used purely for decoration, which is, they add no additional meaning to the page and are just present for pure aesthetics. Select all such images and click "NEXT".
If you aren't sure whether an image is decorative or not, determine if any information would be lost if the image was removed from the page entirely.
Step 3: Text Images
You will be asked to select any images with embedded text. If the image itself contains any text at all, select that image.
Logos are exempted so if the logo contains text like the name of your company, those should not be selected.
Step 4: Accuracy
Next, you will need to check to see if the accessible name (such as alt text) is actually descriptive of the image. The accessible name displayed should accurately describe the meaning conveyed by the image without being overly verbose. For example, the accessible name should not contain "Image of" which is information already conveyed by assistive technology. Go through each image and select "Yes" for all the images that do have accurate/descriptive accessible names and "No" for those that do not.
Running in Automated Mode
When automated IGT mode is enabled, the Images IGT includes an image selection step before AI begins its analysis. This gives you direct control over the scope of your test.
Step 1: Select images to test
Before AI analysis begins, you'll see the images found on the page, grouped by similarity. Select the images you want to include in your test, then click Next to proceed.
You don't need to test every image. Selecting one representative image from each group is usually enough to validate a pattern, and testing fewer images consumes fewer AI credits — helping your team get the most out of your monthly credit allocation.
Step 2: AI analyzes your selected images
AI automatically evaluates each image you selected, determining:
- Purpose: Whether the image is decorative or informative
- Accessible name: Whether informative images have an accurate, descriptive accessible name, suggesting alternative text where it is missing or inadequate
- Images of text: Whether the image contains embedded text
Once analysis is complete, you'll be taken to the review screen to confirm AI's classifications, make any corrections, and finalize your test. See Automated IGTs for details on reviewing results, making corrections, and completing your test.
What it tests for
The Images IGT tests for:
- Decorative images
- Images containing text
- Images having meaningful alternatives that describe the meaning of the image
