Erlend | 15 years ago | on: Ask HN: image scaling on the fly

Sorry, I wasn't clear enough earlier.

I have used imagemagick/GD previusly, but there are some hassle involved in setting up this for each project/client (cron job for cleaning up thumbs, space considerations, not all ISP I use for clients have GD installed etc)

I agree that writing an ad-hoc image scaler is simle.

However, writing a quality general one that handles different formats, image quality, aspect ratio, smart cropping etc..is not trivial.
