IMGSHR

Simple image gallery sharing application. Galleries are creatable by everyone and available with a token in the URL. Everyone with the correct URL can change the gallery name, upload images and set their title. On creation, a boss token is generated, which can be used to delete the whole gallery, single pictures or make the gallery read-only later on.

You can test this at https://imgshr.space!

Features

Galleries are shared via secret token in URL (e.g. https://imgshr.space/!Njg4NThi)
Galleries are editable by everyone or -- when they are configured to be read-only -- only with a boss token (URL)
Pictures can be shared with token URLs to prevent giving away a gallery's token
EXIF data is read and shown
Pictures can be rated
Infinite scrolling on gallery page
Lazy image loading
Responsive design
Tagging of images
Filter by tags, date, rating
Automatic labelling using self-hosted Convolutional Neural Network (Inception v3 model)
GitHub login for taking track of galleries and gallery administration
Device token authentication for galleries
Symmetric client-side encrypted galleries with sharable secret based on libsodium (XSalsa20 for encryption, Poly1305 for authentication)
"Responsive Images Service": Options like resize for inclusion in third-party sites
Transparent conversion of images (to avif or webp) if browser supports these formats
Milestones can be set by gallery and shown on images (e.g. for showing time since a certain event on photos)

Development

nvm use
npm install -g yarn

Deployment using docker

Initial setup

Clone the source code:

git clone https://github.com/nning/imgshr.git
cd imgshr

Change the MySQL root password and the admin login credentials in .env and config/settings.yml.

Then generate a Rails secret key and paste it into .env:

./deploy.sh run web rails secret

Now start up all services (in background):

./deploy.sh up -d

The docker volumes deploy_db, deploy_redis, and deploy_storage hold the production data; make sure, you do not lose them.

The log can be followed with:

./deploy.sh logs -f

Update the code

./deploy.sh down
git pull
./deploy.sh up --build
