How to Use the Plugin
Plugin settings
In your WordPress admin panel in the plugin’s settings (Imagerr AI > Settings), you will find various options like, for example:
- Auto Generate on Upload
- Generate Title
- Generate Caption
- Generate Description
- Language
- Meta Prefix
- Meta Suffix
Use on one particular image
Instructions for using the plugin on one particular image
Simply navigate to your WordPress media library (Media > Library), click on a particular image, and click on the blue button “Update with Imagerr,” and you are all set up.

Auto generate on upload
You can automatically generate the alt text (and/or the meta title, caption, and description too) for all your new images when they are uploaded to your media library. You can activate this feature in your WordPress admin panel in the plugin’s settings (Imagerr AI > Settings).

Bulk generator
You can also apply this to the images that already have alt text by ticking the first checkbox at the bottom.
If you tick the second checkbox, “Replace on posts,” too, the plugin will search for each image across all post types and automatically update its alt text everywhere it is used – not just in the media library. This ensures that reused images always show the most accurate and updated alt text across your entire website. However, plase be aware of that enabling this option will increase the total time that will be needed to process all images. For example, if you want to process 5,000 images at one time, it may take even a few hours.

Note: Do not close your browser window during the bulk generation process. If you need to stop the process, click on the “STOP” button (after that it takes a couple of seconds while the process stops).

Bulk update your Media Library
You can bulk generate alt texts for multiple images chosen in your WordPress image media library.
Smart tip: Before using this feature, you can update the SEO Keywords Settings of the plugin (mentioned further down in this documentation) and, for example, add an SEO keyword that you want to use for this batch of images. For example, in my case, I will add a “Spain” keyword for my current batch of images. After that, you can repeat this process and add different keyword(s) or different SEO keyword settings that you will need for your other images.

You can either select multiple images in the WP media library grid view:

Or you can tick the checkboxes for multiple images in the WP media library list view:

And you can also filter your media library images without alt text or with alt text, like you can see on the screenshot below:

After selecting your images, click on the “Generate alt text with Imagerr” button, and you will be redirected to the bulk generator page on which you can run the bulk generator for the selected images.

Bulk update multiple posts/pages
Just select the particular posts/pages, and after that choose the “Bulk generate alt text” option from the bulk actions dropdown:

SEO keywords settings (optional)
At the bottom section of the plugin’s settings, you will find the SEO keywords settings. These settings allow you to predefine SEO keywords that you would like to have included in your generated alt texts. This can be helpful for your SEO. Please note that all these settings are optional and you may not even need them.
You can do the following:
- Use the WordPress post or page title on which the particular image is used.
- Use focus keywords or keyphrases from SEO plugins’ post or page settings. This works with all major SEO plugins that include RankMath, Yoast SEO, AIOSEO, SEOPress, and Squirrly.
- Add your own custom SEO keywords that you want to use (optional, maximum 3, separated by commas).
- Add negative keywords that you want to avoid using (optional, maximum 3, separated by commas).
