Build static HTML galleries from local photos & videos.

- thumbnails & multiple resolutions for fast previews
- only rebuilds changed files: it's fast!
- supports custom styles
- uses relative paths so you can deploy the pages anywhere
- works great with Amazon S3 for static hosting

## Example gallery

You can [view a sample gallery here](http://rprieto.github.io/thumbsup).

[![screenshot](https://raw.github.com/rprieto/thumbsup/master/screenshot.jpg)](http://rprieto.github.io/thumbsup)

## Required folder structure

Any folder with photos and videos!
`thumbsup` currently supports 1 level of subfolders, where they each become a gallery.

```
input
  |
  |__ paris
  |    |__ img001.jpg
  |    |__ img002.jpg
  |
  |__ sydney
       |__ vid001.mp4
       |__ img003.png
```

## Setup

### As an npm package

**Requirements**

- [Node.js](http://nodejs.org/): `brew install Node`
- [GraphicsMagick](http://www.graphicsmagick.org/): `brew install graphicsmagick`
- [FFmpeg](http://www.ffmpeg.org/): `brew install ffmpeg`

*Note: there currently is [an issue with Ubuntu 14.04](#27) if you build `ffmpeg` from source. Please upgrade to 14.10 and install it with `apt-get`.*

**Installation**

```bash
npm install -g thumbsup
```

**Creating a basic gallery**

```bash
thumbsup --input ~/photos --output ~/gallery
```

## Expected output

If everything worked well, you should expect:

```bash
$ thumbsup [args]

  List all files      [===================] 6/6 files
  Update metadata     [===================] 6/6 files
  Original photos     [===================] 6/6 files
  Original videos     [===================] 6/6 files
  Photos (large)      [===================] 5/5 files
  Photos (thumbs)     [===================] 5/5 files
  Videos (resized)    [===================] 1/1 files
  Videos (poster)     [===================] 1/1 files
  Videos (thumbs)     [===================] 1/1 files
  Static website      [===================] done

  Gallery generated successfully
```

`thumbsup` keeps track of which files need updating.
Re-running the command above when nothing has changed will show the same
output but only take a second, even on a gallery of thousands of photos and videos.

## Configuration

The following args are required:

- `--input <path>` path to the folder with photos / videos
- `--output <path>` target output folder

And you can optionally specify:

- `--title [text]` website title (default: `Photo gallery`)
- `--thumb-size [pixels]` thumbnail image size (default: `120`)
- `--large-size [pixels]` fullscreen image size (default: `1000`)
- `--original-photos [true|false]` to allow download of full-size photos (default: `false`)
- `--original-videos [true|false]` to allow download of full-size videos (default: `false`)
- `--sort-folders [name|date]` how to sort the folders/galleries (default: `date`)
- `--theme [name]` name of the gallery theme to apply (default: `default`)
- `--css [file]` CSS or LESS styles to be applied on top of the theme (no default)
- `--google-analytics [code]` code for Google Analytics tracking (no default)

*Note:* all paths are relative to the current working directory.
For example:

```bash
thumbsup --input "/media/photos" --output "./website" --title "My holidays" --thumb-size 200 --large-size 1500 --full-size-photos true --sort-folders date --css "./custom.css" --google-analytics "UA-999999-9"
```

You can also save all your arguments to a `JSON` file:

```bash
thumbsup --config config.json
```

**config.json**

```js
{
  "input": "/media/output",
  "output": "./website",
  "title": "My holiday",
  "thumb-size": 200,
  "large-size": 1500,
  "original-photos": true,
  "original-videos": false,
  "sort-folders": "date",
  "css": "./custom.css",
  "google-analytics": "UA-999999-9"
}
```

## Generated gallery structure

The generated static website has the following structure:

```
website
  |__ index.html
  |__ sydney.html
  |__ paris.html
  |__ public
  |__ media
  |    |__ original
  |    |__ large
  |    |__ thumbs
```

##  Themes

The `--theme` flag allows you to select a style for the generated gallery.
The only theme so far is called `default`, but please submit more ideas to share!

Some themes have [LESS](http://lesscss.org/) variables that you can customise.
Check [THEMES.md](THEMES.md) for more details.
Simply use the `--css` option and pass a LESS file with your values, e.g.

```less
// thumbsup --css custom.less

@myvariable: #cef9b6;
```

## Deployment

The simplest is to deploy the media and generated pages to S3 buckets on AWS using the [AWS CLI tools](http://aws.amazon.com/cli/).

- `aws s3 sync ./generated/website s3://my.website.bucket --delete`

You can also use [s3cmd](http://s3tools.org/) which offer a few more options.

- `s3cmd sync --config=<credentials> --delete-removed --exclude-from <exclude-file> ./generated/website/ s3://my.website.bucket/`


## Password protection

Amazon S3 buckets do not offer any type of authentication. However you can choose to deploy to another web server that offers password protection, such as HTTP Basic Auth.

An alternative is to deploy the galleries to UUID-based locations, like Dropbox shared galleries.

## Dev notes

To create the sample gallery locally:

```bash
npm run clean      # clean the output
npm run example    # build the gallery
npm run open       # open it in the browser
```
