Show HN: Kraken.io – image optimization service

Just had a thought. If I generate 8MB PNG files with noise in them and upload 1000 of such files, your servers will choke.

Maybe you should charge per MB.

You are right, our optimization workers will have a lot of work to do to optimize those images. In that case we recommend the use of "callback_url" option to eliminate the possibility of a request timeout.

No, I mean it can be used to DoS you. Give it a try. Optimizing even one 8MB noise PNG is a huge amount of CPU work.

I've just tried compressing a 12 meg png file with pngcrush locally (generated with `convert -size 1000x2000 xc: +noise Random noise.png`, it only took a few seconds and didn't tax the processor much. Maybe pngcrush handles it better than other things but that didn't seem onerous.

I would guess that the service does something more along the lines of `pngcrush -brute` which is significantly more taxing.
