Looking for Image Library quick browser / editor

We want to make our K-8 school’s website ADA-compliant, starting with making sure all 1,400 images have good ALT text. But opening each image separately will be a real chore so I”m looking for an alternative. I don’t want a plugin that will automatically insert ALT text, because most images have unreadable filenames.

I would love to find an Image Library browser plugin that would display the images in a column on the left with the ALT text boxes in a column on the right, so that I can quickly browse through the library and manually enter good ALT text.

Thanks for any hints.
