Photo sharing applications are no longer just about manipulating and uploading photos to the cloud. The success of Instagram has shown that photo sharing apps need a way for users to interact in real time, one where users can subscribe to channels and notify other users that they’ve uploaded a new photo.
The Cloudinary API allows users to upload images to the cloud, manipulate them with different effects and filters, and deliver the images through a CDN. PubNub powers the real-time interaction within the app, allowing users to subscribe to different channels that will send notifications when a photo is uploaded.
Using the Cloudinary API and PubNub together, you can build a real-time photo sharing application. No complex coding required.
For a detailed walk through and all the code you need, check out the Cloudinary blog. Additionally, a working demo can be found here.
