DP ALTerminator adds missing or empty ALT tags to your content images.
Thanks to various shortcodes such as <code>%%DP_TITLE%%</code> or <code>%%DP_DATE%%</code> it’s pattern can be easily customized (you can mix plain text elements with shortcodes to create complex patterns)
DP ALTerminator works when ALT tags are missing or when they are empty. Sometimes WordPress itself, visual editors, and so on, leave an ugly <code>alt=""</code> which is useless and not always recognized by other famous ALT tag managers.
DP ALTerminator works only with content images ($content variable), because I didn’t want to alter “extra” images, like widgets, logos, menu icons and so on (most of the times, you want to manually edit their ALT or leave it empty)

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.
<h4>Plugin actions in wordpress</h4>
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.

Update Image Tag Alt Attribute

fast


	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.




Lots of Potential

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.
