Picture viewing web page

I wanted to share pictures taken from our Antony and Cleopatra Reading this week and decided to create a page with thumbnails and links to the full pictures. Sure there are programs out there that do it and host for you, but it is so hard to get at the full res images and I guess they just annoy me, so I wanted to do it old school. Also I figure it is a good opportunity to practice some of the skills I have been exploring lately.

1) Write a shell script to shrink the image files and create thumbnails. Well actually putting it in a batch file is overkill, but it’s the first shell script I have created, pretty simple:

  • create a file with .sh extension and give it executable permissions with “chmod -x [name].sh”
  • add “#!/bin/sh” at the top
  • add commands that you want to execute from the commandline below

2) shrink all the files, I used imagemagick (convert) to do this the -thumbnail option is designed for creating thumbnails and the x300 makes the final image 300 pixels tall and maintains the aspect ratio. The command I ended up using was:

ls *.JPG | xargs -0 | xargs -I {} -n1 convert {} -thumbnail x300 thumbs/thumb_{}

3) I used a little java script to generate the web page.

  • first created a list of all the files using underscore.js, then
  • used d3.js to populate the appropriate number of links to display the thumbnails as links to the full size images

The resulting picture page is not fancy, but functional.
