Autosmush scans your S3 bucket, runs each file through Smush.it, and replaces your images with their compressed versions.

I think I'm in love.

Depending on how many images you have. Doesn't that mean that it has to download each image and then re-upload them? Could be quite a cost for minimal savings if you have a large number of images to store.

Edit: I'm talking about 20,000+ product images, not the images or files associated with a layout.

Could be, could be a large saving for minimal investment in time+money. depends on how much downloading of the images occurs normally.

The blog post mentions how he fixes the issue (at least for repeated runs)

For me this isn't about saving money, it's about load time.

Wouldn't it be free (or close to it) if you run it on an EC2 instance?

I just used Smush.it to optimise a couple of images on http://lanyrd.com/ (the logo and the background image) and it knocked a good 5KB off the page load - not too bad at all.

Our filenames are generated from the truncated SHA1 hash of the file contents, so logo.png becomes logo.16c7e567.png - which means we can safely set a far-future expires header and serve through Amazon CloudFront without worrying about changes to the images, JavaScript or CSS not propagating to the live site.
