In WordPress, changing image alt text is a straightforward process. Here are the steps you need to follow:
Log into your WordPress dashboard.
Navigate to the page or post where the image is located.
Click on 'Edit' for that particular page or post.
Within the editor, click on the image that you want to change the alt text for.
This will open up a menu on the right side of the screen. In this menu, look for the 'Alt Text' field under 'Image Settings'.
Enter your new alt text into this field.
Once done, remember to click 'Update' for the changes to be saved.
Here's a code snippet showing HTML structure of an image with alt text, within the WordPress editor:
The `alt` attribute contains the alt text. You don't generally have to work directly with the code in WordPress as the CMS provides user-friendly interfaces for these tasks, but if you needed to add alt text programmatically, that's how it would appear in the HTML.
Remember that the alt text is important for SEO and for users who can't see the image for whatever reason. It should provide a clear description of the image.
