photo-gallery

A blocks that allows you to display a photo slideshow on a webpage over a web server. Out of the box you can use Google Photo Albums, Dropbox Photo Album and Apple Photos. The images are downloaded automatically and auto updated in case of changes.

Supported Albums

Google Photos Albums

Go to https://photos.google.com and select the album that you want to share.

Click in the share button, click in the Create link button and copy the the url.

Dropbox Photo Albums

On the dropbox website, go to the folder that contains the photos and click on Share Folder and then Copy link. This will the URL you will need to add to balenaCloud.

Apple iCloud Photo Album

Create a photo album and copy the share url, similar to https://www.icloud.com/sharedalbum/#ALBUM-ID

USB drive Photo Album

Place your photos on a USB stick and plug it into the Raspberry Pi. Each time all previous existing photos will be removed and replaced by the new ones.

• Set GALLERY_URL to USBDRIVE to use this mode.
• Make sure to update CRON_SCHEDULE accordingly or else image changes will only be picked up at reboot.

Usage

Include this snippet in your docker-compose.yml file under 'services':

photos:
  image: bh.cr/balenalabs/photo-gallery-<arch>/<version> # where <arch> is one of aarch64, armv7hf, rpi or amd64 and <version>(optional) is a specific version of this block
  privileged: true # required for UDEV to find plugged in peripherals such as a USB mouse
  restart: always
  ports:
    - "8888"

e.g For running on Raspberry Pi 3B+ which is armv7hf use image:bh.cr/balenalabs/photo-gallery-armv7hf

You can also set your docker-compose.yml to build a Dockerfile.template file, and use the build variable %%BALENA_ARCH%% so that the correct image is automatically built for your device.

docker-compose.yml

version: "2.1"
services:
  photos:
    privileged: true
    restart: always
    build: ./
    ports:
      - "8888"

Dockerfile.template

FROM bh.cr/balenalabs/photo-gallery-%%BALENA_ARCH%%

Supported Architectures

• armv7hf
• rpi
• aarch64
• amd64

Setting up the photo album

• On balenaCloud, go to Device variables D(x) and add the following:

ENV VAR	Description	Options	Default
PORT	Web server port.		8888
GALLERY_URL	Gallery URL for google photos, dropbox images, apple photos or usb drive.
GALLERY_SLIDESHOW_DELAY	Slideshow delay in milliseconds		10000
GALLERY_IMAGE_STYLE	Contain shows the entire image on the screen. Cover zooms the image filling the entire screen.	contain, cover	cover
GALLERY_EFFECT	Transition effects	fade, horizontal, vertical, kenburns, false	fade
CRON_SCHEDULE	Cron scheduler to reload images to get changes		0 */12 * * *
SHUFFLE_SLIDESHOW	Shiffle images to display randomly	true, false	false
RESIZE_WIDTH	* Resize image width or height (larger side) in pixels		1000px
COMPRESS_QUALITY	* Image compression	0 - 100	90

* Only available for iCloud photos

Note that after some performance tests on the Raspberry Pi 2 & 3, the combination of GALLERY_IMAGE_STYLE = contain and GALLERY_EFFECT = fade or kenburns can make the transition effects choppy.
