-----------------------------+--------------------
 In order to improve Photo Directory integration in Gutenberg through
 Openverse, the direct image URLs needs to set `Access-Control-Allow-
 Origin="*"` headers.

 Gutenberg Openverse media inserter tries to download the images from
 providers (such as Photo Directory) and add it to the Media Library. When
 the direct image URL does not have a CORS header, the following error is
 thrown:

 ''This image cannot be uploaded to your Media Library, but it can still be
 inserted as an external image.''

 [[Image()]]


 This is the code in Gutenberg that shows this modal when an image cannot
 be fetched due to CORS issue:

 https://github.com/WordPress/gutenberg/blob/6db51a6ee92db6c3324a875135656861bbd9e55d/packages
 /block-editor/src/components/inserter/media-tab/media-preview.js#L145-L149

 Can we add the CORS headers to the image URLs?
