    exit 0
fi

This custom action allows you to host your screenshot on this free online hosting service, so that you can share it easily with other people. Imgur automatically generates a tiny, medium, and full-size image of your screenshot, which can be used to create thumbnails pointing to the full size screenshot.

Save the following script somewhere and set as command: <somewhere>/imgur-upload.sh %f <CLIENT ID>, you need to register at Imgur and obtain your client id.

#!/usr/bin/env bash

URL='https://api.imgur.com/3/image'
SCREENSHOT_PATH=$1
CLIENT_ID=$2

if [ -z "$SCREENSHOT_PATH" ] || [ -z "$CLIENT_ID" ]; then
    zenity --error --text="Arguments are missing"
    exit 1
fi

if ! command -v jq >&2; then
    zenity --error --text="jq: command not found!"
    exit 1
fi
