How to allow empty title for attachments?

Without a post title, Attachments become significantly harder to use as they no longer have a title that can be clicked on.

If you’re processing attachments and generating html manually I recommend using another piece of attachment meta, or just filling in appropriate titles, after all an image is a picture of something, let that something be its name, there’s nothing stopping duplicates either.

If you really must remove the title, go to the html tab and manually remove it from the tag. Else put in a placeholder character such as ‘-‘.

Ofnote, attachments are posts too, and that means they have post meta. You could add a checkbox to the edit attachment page, allowing you to toggle on and off wether the attachments title is displayed or not.
