Update Image Tag Alt Attribute


This is an alt text modification plugin. It will take all empty alt tags and create a tag based upon the page they are attached to. This is best used when you have properly named files or have loaded images into the library in bulk.

Plugin actions in wordpress

This plugin searches for all images within the library which are missing alt-text attributes. The alt text will be chosen from page or post title elements if the image is attached to a page or post. Otherwise, file name will be used as the alt-text attribute of unattached images in media library.

The purpose is to help describe those images as best as possible for interpretation by search bots. Moreover, after updating, the plugin creates a file which lists all the images that was found to be missing alt-text attribute and then updated with alt-text. This will allow you to then tweak where necessary.

It did update all empty ALT-tags but it doesn't used chars like å, ä and ö. It replaced them with a and o. Edit: This plugin use the filename to create ALT-tags, not the post title.

Could definitely use some improvements through an update. The good part, it updates your empty alt tags. The bad parts: the list it generates isn't clickable so you still have to go search for the images to tweak their content, the alt tags often have spaces removed, so a post titled "My Summer Vacation" seems to throw "mysummervacation" onto associated images as the alt text, and finally, instead of placing this in Settings or Tools (like the screenshot shows), it adds a whole new "Maui Marketing" area to navigation bar in WordPress, which is unnecessary.

The plugin is concatenating the terms into the alt tag when it's multiple words. So "red dog" becomes "reddog". A whitelist/blacklist terms feature would be great so that you could skip images with filenames like "screenshot". An ajax edit option would be great on the output list of media that's been updated. The plugin stalled on a large site that I tested it on, never getting past "Loading...". Would be worth it to chunk the output by media ID.

I was wondering why my SEO rating for some articles was going down...until I discovered this plugin had decided to chance the alt tags for the featured images of my articles to the name of the file, instead of the CAREFULLY selected and filled keyword alt tags.
