'Slink' solves the problem of safely sharing images with friends, family, and colleagues for free, allowing you to create a private self-hosted environment
If you want to share images only with close family, friends, colleagues, etc., `` Slink '' is available as a simple image sharing system that can be self-hosted.

◆How to install Slink
This time, we will build an environment with Docker Desktop and Git Bash for Git for Windows on Windows 11. Execute the following command in any folder to create a working folder for Slink and move to the folder.
mkdir slink-app && cd slink-app
Create a folder to store settings and image files.
mkdir slink/var/data
mkdir slink/images
Replace 'IP_ADDRESS' in the following command with the IP address of the PC that will start the container and run it.
docker run -d \
--name slink \
-p 3000:3000 \
-v ./slink/var/data:/app/var/data \
-v ./slink/images:/app/slink/images \
-e ORIGIN=http://IP_ADDRESS:3000 \
-e TZ=Asia/Tokyo \
-e USER_APPROVAL_REQUIRED=false \
-e IMAGE_MAX_SIZE=15M \
-e STORAGE_PROVIDER=local \
anirdev/slink:latest
Open your browser and access http://【IP_ADDRESS】:3000 to display the Slink homepage.
Access 'http://【IP_ADDRESS】:3000/profile/signup', enter your username in 'Username' and your email address in 'Email Address' in the user registration form, enter your password in 'Password' and 'Confirm Password', and click 'Create Account' to create a user.
To promote the created user to administrator, replace 'EMAIL_ADDRESS' with the registered email address and run the following command.
docker exec -it slink slink user:grant:role --email=EMAIL_ADDRESS ROLE_ADMIN
Access 'http://【IP_ADDRESS】:3000/login', enter your username or email address in 'Email or Username', enter your password in 'Password', and click 'Sign In'.
Once you log in, a menu and image list page will be displayed.
◆ Collaboration with ShareX
You can take a screenshot and upload it directly to Slink. To set it up, click on the area where your Slink account is displayed, and a menu will appear. Click on 'External Integrations.'
Click “New API Key”.
Enter any name in 'Key Name' and click 'Create API Key'.
An API key will be created, so click 'Download ShareX Config' to save the configuration file.
Double-click the saved configuration file.
The Import Settings File dialog box will appear, so click 'Yes'.
Under 'Upload destination,' check 'Custom image uploader' under 'Image uploader.'
Under 'Post-capture tasks,' click 'Upload image to host' to enable it.
Once captured, the image will be automatically uploaded and displayed in 'Upload History'.
Uploaded images are first recorded in each user's 'Upload History,' and users must then sort them into collections or set their public settings.
◆About users
There are two types of user permissions: 'User' and 'Admin.' There is no group function, and no function to assign viewing permissions or capacity limits to each user.
Slink has enough functionality to be used as a simple shared album. However, to access via HTTPS, you will need to set up a separate reverse proxy.
