SMS and MMS Photo Filters with Twilio + Aviary

The text discusses the integration of Aviary's photo editing engine with Twilio's communications API. This allows developers to create an SMS-based photo editor that can accept and respond to both SMS and MMS messages, rendering images with filters using Aviary's server-side rendering endpoint. The example code demonstrates how to use the Aviary node.js wrapper to interact with the server-side API and generate a TwiML response to send the rendered image back to the sender via SMS or MMS.
