Usage

Step 1: Generating your JSON file.

Prior to use this program you will need to download your gallery information into a target.json

To generate the target.json you can perform a cURL request like the one below Note: The file will be generated in the folder your terminal is currently in!

To find your cookie, go to https://prntscr.com/gallery.html and follow instruction 1.1

/!\ You must be logged into your account before going to step 1.1 !

Step 1.1: Getting your __auth cookie

Browser	Action
Firefox	Step 1: Shift+F9 Step 2: Click on Cookies option on left" Step 3: Select the cookie provider: https://prntscr.com/ Step 4: Copy the value associated to __auth
Chrome	Step 1: F12 Step 2: Click on Application at the top Step 3: Click on Cookies option on left Step 4: Select the cookie provider: https://prntscr.com/ Step 5: Copy the value associated to __auth

Step 1.2: Preparing the request

Edit the request with your own __auth cookie

-H 'cookie: __auth=<YOUR COOKIES>'

Request

curl 'https://api.prntscr.com/v1/' \
  -H 'authority: api.prntscr.com' \
  -H 'pragma: no-cache' \
  -H 'cache-control: no-cache' \
  -H 'accept: application/json, text/javascript, */*; q=0.01' \
  -H 'user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.102 Safari/537.36' \
  -H 'content-type: application/json' \
  -H 'origin: https://prntscr.com' \
  -H 'sec-fetch-site: same-site' \
  -H 'sec-fetch-mode: cors' \
  -H 'sec-fetch-dest: empty' \
  -H 'referer: https://prntscr.com/gallery.html' \
  -H 'accept-language: fr-CA,fr;q=0.9,fr-FR;q=0.8,en-US;q=0.7,en;q=0.6,it;q=0.5,ru;q=0.4' \
  -H 'cookie: __auth=<YOUR COOKIES>' \
  --data-binary '{"jsonrpc":"2.0","method":"get_user_screens","id":1,"params":{"count":10000}}' \
  --compressed > target.json

Note: This request will only retrieve your last 10.000 screenshots.

Step 1.3: Performing the request

To perform the above requeste you must have a terminal capable of using cURL. Powershell can work but unless there is lot of demand I won't explain how to proceed

OS	Terminal	Support	Working	Using cURL
Windows	PowerShell	❌	Likely Yes (Untested)	❌
	Git Bash	✔️	✔️	✔️
Linux	Bash Terminal	✔️	✔️	✔️
MacOS	Terminal	✔️	✔️	✔️

Step 2: Cloning the repository

Once you have your target.json file, clone or download LighshotGalleryDownloaded-CLI.

git clone https://github.com/Wipie/LightShotGalleryDownloader-CLI.git

Step 3: Installing depedencies

After cloning get into the root repository and open a terminal to install node depedencies

npm install

After installating depedencies, move the target.json file into the root of the program your folder should look like this

.
├── node_modules                
├── images                      # Folder where downloaded image will output.
├── package-lock.json    
├── package.json        
├── index.js                    # LightshotGalleryDownloader-CLI
├── target.json                 # Your target.json
├── LICENSE
└── README.md

Step 4: Run the program

Finally in a terminal run the program

node .

If you want to start at a specific index or resume where you were you can use the following

node . <number> e.g node . 100 Will start at 100 

Let it run depending on how much screenshots there is it might take a LONG time.

Troubleshooting

If during download you are getting error while downloading, navigate inside index.js and uncomment Line 18, wipe the /images/ folder and try again. It will take longer but you won't be timed out by prntscr.com
