EasyAltText

Tested minutes ago with WP 4.5.2. Like many, I only realised recently that alt texts are important. I needed a plugin that allowed me to quickly display all the alt tags so that I could add/edit the missing or vague ones. This allowed me to do the job nice and easy. Big thanks to the author, as opening each image in the media library would have been too much of a chore.

Your plugin is awesome. It's so simple that it's amazing. I needed a similar feature for a client, I was able to rewrite some parts to make it fit with polylang in maybe half an hour without headaches. Seriously, this plugin could be a killer one with some work cause title and alt tags are so hard to set in WP.
