133A [mod's `Image`](https://code.claude.com/docs/en/plugins/mods/reference#elements) needs the `allow-passthrough` and `focus-events` lines, along with the other [requirements for drawing inside tmux](https://code.claude.com/docs/en/plugins/mods/gallery.md#draw-an-image-inside-tmux). After you add the lines, also detach from tmux, attach again, and restart Claude Code.
