Avatar Montage

Create a tiled montage (or collage) of GitHub Avatar images for use in all hands and other "welcome" or "thank you" slides

This repo contains two tiny bash scripts in the scripts/ directory. One to download avatars via curl, the other to create the montage via ImageMagick's montage command.

Here's an example of what the resulting montage looks like using the first 98 GitHub users by user ID:

Of course you can customize the output. See below for details. Don't need to control the output or are looking for something simpler? Check out @jhutchings1's hosted Thank you builder.

Usage

1. Clone this repo locally and cd into the directory
2. Add a list of GitHub handles (without the @) to a handles.txt file, one handle per line
3. Run script/download to fetch the avatars
4. Runscript/create to create the montage
5. Use the resulting montage.png file in your presentation

Requirements

To run the scripts, you'll need:

• curl, and
• imagemagick

Note: You can install both on MacOS with brew bundle

Customizing the output

You can customize the output by passing additional arguments to script/create, e.g., script/create -tile 10x to force the montage to be 10 images wide. See the ImageMagick montage documentation for a list of available options.

Credit goes to @martinwoodward for his "very quick ruby script to create a bash script that will create a montage" for the idea, and for pointing me towards the ImageMagick montage command.
