I was really hoping this would work on the server-side, too. It didn't. :-( Or maybe I configured something wrong?
Here's what I found:
$ git clone https://github.com/yahoo/gifshot.git
$ cd gifshot
$ npm install
$ node
> var gifshot = require('./build/gifshot')
> gifshot.createGIF(
... {'images':['random-image.png'],
..... 'text': 'Test'},
... function(obj) {
..... console.log('Done!');
..... console.log(obj);
..... })
Done!
