tmux-paste-image.sh

#!/usr/bin/env bash
#
# Paste the macOS clipboard image into the current pane.
# - If the pane looks like a Claude Code prompt, sends `/image <path>` + Enter
# - Otherwise, pastes just the path so you can use it elsewhere
#
# Requires: pngpaste (brew install pngpaste)
#
# NOT currently bound — Claude Code handles clipboard paste natively now.
# To activate, add to ~/.tmux.conf:
#   bind V run-shell "~/projects/dotfiles/tmux-paste-image.sh"
# Then reload tmux config and use `prefix + V`.
