1.1.0

Setting a link, without a code to memorise:

• New "Do not link this image" tick box beside the URL field, in the media modal and in the attachment editor. It stores the same [none] marker underneath, so galleries built with the old plugin keep working and typing [none] by hand still does exactly what it always did.
• The link fields now sit in a box of their own in the sidebar of the full attachment editor, alongside every other attachment setting. They used to be laid out along the bottom of that screen in a table whose labels did not line up with their own fields, leaving the URL box floating above its label. Declared with show_in_edit => false, so the media modal is untouched.

1.0.0

First public release.

Point each image of a classic [gallery] at any URL you want. The link is set once on the image and used everywhere that image appears.

• Per-image link, target, lightbox handling and extra CSS classes, with site wide defaults for anything the image does not decide.
• [none] for an image that should not be clickable.
• Reads the same attachment fields as the discontinued WP Gallery Custom Links, so galleries built with it keep working with no re-editing, including its per-gallery shortcode attributes and the wpgcl_filter_raw_gallery_link_url filter.
• Gallery link column and filter in the media library.
• Site audit, link verification and CSV export in the Tools tab.

Better than the original: URLs are escaped on output, where the old plugin had a stored XSS hole; the gallery renders once instead of twice, so gallery IDs and CSS stay correct; no JavaScript is needed to keep lightboxes away; and every new window link gets rel="noopener".

Installing: download legacy-gallery-links.zip from the assets below, then upload it in Plugins → Add New → Upload Plugin. Use that one rather than the "Source code" zip, which unpacks into a folder with the version number in its name.
