So just clarify for the thickies like me:
Updating the media library DOES NOT update an embedded image in a post or page!!!!!! Grrrrrrrrhaa!
I uploaded 1170 images into my media library embedded them in to numerous posts, then discovered they all need to be SEO'ed by including the Alt. text on all images.
I can either update the image directly in the post (BUT the corresponding image in the media library will not change).
Update the files in the media library then RE-embed them into all my posts ?
Is there any plugins out there to fix this issue? IE to force the embedded images to take the media library attributes?
