What are the best practices for dynamic image processing?

Hi Indie Hackers! I will explain how we do dynamic image processing at image4io.

☻ Store original image
☻ Set up a high-performance HTTP server with image processing features and connect it to your image store.

Then when an HTTP request comes:

1. Extract image manipulation parameters from URL
2. Fetch original image from storage
3. Apply manipulations with the parameters you extracted from URL
4. Deliver the final image. (Use image CDN)

You can play with the dynamic URL below to dynamically resize image:

http://cdn.image4.io/i4io/w_400/demo-images/hummingbird.jpeg
(Hint: Put w_563 instead of w_400 to change image’s width to 563.)

Here is how we do dynamic image processing at image4io.
