Easy to move images around. Responds well to screen size changes. But to be able to make the images individually clickable, I may have to use a plugin. Or I could fake it out: edit the html, changing the data-link for each image to the external URL wanted, and then choose link to “attachment page” in the gallery block settings. (Or change data-full-url and link to the “media file”.)
Specifically, the parameters for the img tag in the gallery (which is a class for the figure tag) include
- src: this is the “file URL”. (Editable on the edit media page, but maybe you shouldn’t change once you have used the image somewhere!)
- alt: text to show if viewer is not loading images by default
- data-id: this is the post number, which you can find in the browser URL when you are in edit mode. I don’t know another way to discover it. It cannot be changed.
- data-full-url: this is (by default) also the “file URL”, a.k.a. the “media file”
- data-link: this is (by default) the permalink, a.k.a. the “attachment page”. (Editable on the edit media page; perhaps it is a good idea to make this pretty.)
- class: this seems to be “wp-image-” . data_id
