There are a lot of Raspberry Pi camera projects out there that capture photos. Obviously. I’ve found a nice PHP script that lets you view these photos directly from the Pi via a web browser. The script is called “Single File PHP Gallery” and it’s free.
Single File PHP Gallery is a web gallery in one single PHP file created by Kenny Svalgaard. All you have to do is copy the script to any directory containing images to make a gallery. This makes it perfect for quickly adding some fantastic functionality to your Pi camera projects with a minimum of effort. Why spend days writing your own image presentation system when you can do it it 5 minutes?
Sub directories are treated as sub galleries and the script can generate thumbnails for images and directories automatically.
Single File PHP Gallery does not require any configuration or programming skills to use. You just drop the file into your photo directory and you are ready to go. The only requirements are that your Pi is running a web-server and your photos are in a directory visible to that server.
Don’t worry. That’s easy to setup if you haven’t already and it will be explained below.
- Free for private non commercial use
- Uses no database
- Automatically creates thumbnails
- Displays EXIF information
- Option to add watermarks
- Supports JPG, JPEG, PNG and GIF
- Unlimited numbers of sub galleries
Step 1 – Install Lighttpd Web Server
First you need an active web server running on your Pi. You can use any PHP enabled server but I use Lighttpd and instructions for setting this up can be found in my Install a Raspberry Pi Web Sever article. Make sure you get the test page working before continuing.
Once you’ve completed this step the /var/www directory will be able to serve PHP files. Let’s make a directory for some photos :
Step 2 – Install PHP GD Library
The script makes use of the PHP GD image processing library. To install this you can use the command :
sudo apt-get update sudo apt-get -y install php5-gd
Step 3 – Add Single File PHP Gallery Script
Next we need to download the Single File PHP Gallery script and make sure it is placed in our photo directory. Let’s make sure we are in the home directory :
and then grab the script from the project web site :
Now we need to extract the contents of this archive into the directory that will contain our photos or sub-directories containing photos :
unzip Single_File_PHP_Gallery_4.1.1.zip -d /var/www/photos
You should see the following output :
Archive: Single_File_PHP_Gallery_4.1.1.zip inflating: /var/www/photos/index.php inflating: /var/www/photos/readme.txt
Step 4 – Add Some Photos
You can either use the Pi camera to save files to the /var/www/photos/ directory or you cheat and copy some photos in manually just to test your setup. I copied a set of existing photos into the directory using FTP so I could get some example screenshots.
Step 5 – View The Gallery
In order to test your gallery you need to know the IP address your Pi has on your network. To do this run this command :
sudo ip addr show
You will see a block of information similar to this :
1: lo: <LOOPBACK,UP,LOWER_UP> link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> link/ether b1:11:ab:42:24:2c brd ff:ff:ff:ff:ff:ff inet 192.168.0.45/24 brd 192.168.0.255 scope global eth0
The IP address in this example is 192.168.0.45. Take this IP address and enter it into the address bar of a web browser on another device. You should see the index.php page that is sitting in /var/www/.
Now enter the IP address but this time add /photos/ to the end :
If everything has worked you should see the photo gallery.
Clicking into a folder will show the photos within that folder :
You can also turn on an information panel which will display technical information about the photo :
The thumbnails are generated the first time the page is loaded in a browser. How long it takes to generate will depend on the number of images in the directory and how big they are.
It’s possible to create your own thumbnails if you prefer. This and many other tweaks is explained in the readme.txt file which should have been extracted to the /var/www/photos/ directory.
