# YourImageShare - Flameshot upload script
#
# Captures a screenshot with Flameshot, uploads it to YourImageShare, copies
# the resulting direct link to the clipboard, and shows a desktop
# notification. Bind this script to a keyboard shortcut in your desktop
# environment instead of the default Flameshot shortcut.
#
# Setup:
#   1. export YIS_API_KEY="your-api-key-here" in your shell profile,
#      or create ~/.config/yourimageshare/api_key containing just the key.
#   2. chmod +x yis-flameshot-upload.sh
#   3. Bind this script to a hotkey (e.g. Print Screen) in your DE's
#      keyboard shortcut settings.
#
# Requires: flameshot, curl. Optional: jq (more reliable JSON parsing),
# xclip or wl-copy (clipboard), notify-send (notifications).
