As answered by people managing Codecademy and FireImg.
FireImg's answer:
It's this simple
Original: https://img.fireimg.com/raw-images/demo/mountain.jpg
Resize to 300px: https://img.fireimg.com/demo/images/mountain.jpg?width=300
Resize to 800px: https://img.fireimg.com/demo/images/mountain.jpg?width=800
Resize with query params: https://img.fireimg.com/demo/images/mountain.jpg?width=800
Same image. Different sizes. Just change the URL.
FireImg's answer:
No CC needed until you exceed the free tier
Simple resizing
Works well with any framework, or no framework at all!
FireImg's answer:
We built FireImg after repeatedly running into how complex image optimization can be. Most solutions require setting up pipelines, learning new APIs, and dealing with unpredictable pricing.
For many projects, that felt like overkill. Hand-rolling something always distracted from what actually mattered.
So we built FireImg to be as simple as possible. Upload an image and transform it directly via URL. No setup, no SDK, no managing image libraries. Upload once, then generate and serve thousands of variations by changing the URL, with built-in caching so each transformation happens only once.
As we built it, we kept pushing toward simplicity and removing anything unnecessary. The goal was to make something you can try instantly and understand in seconds.
