Image resizing service (for Rails, or anything really) [closed]

Question
I'm looking for a (ideally self-hosted) service that lets me do something like
<img src="http://image-resizer.domain.com/resize-image/150/100/path/to/image.jpg" />
This service would:
- download http://mydomain.com/path/to/image.jpg (if it hadn't before)
- resize it to 150x100
- strip / squash the thumbnail of metadata (and whatever else is good for thumbnails)
- cache the thumbnail (to disk, or maybe to s3?)
- serve it to the client
- on subsequent requests for that URL, serve the same cached thumbnail
This would allow me
- only have the original image on my site and outsource the thumbnail generation to another service
- allow me to easily create new thumbnail sizes
- should be efficient
Does something like that exist? Would prefer open source, and hopefully either in Ruby or Node.js.
Bonus points for working on a limited amount of diskspace (i.e. so it would only cache, say, 5GB of images).
Solution
I found Dragonfly: https://github.com/markevans/dragonfly
"An on-the-fly processing/encoding framework written as a Rack application."
It's close to what I was looking for, but I'd prefer something totally separate. Dragonfly looks like it needs to be embedded in your Rails application as a Rack app. (Not an option for me, since I'm still on Rails 2.2)
OTHER TIPS
There are a number of SaaS solutions out there:
www.cloudinary.com <-- This is one of the best ones, I've used it extensively!
Image Science may fulfill your thumbnailing needs, although the whole caching, hosting and metadata stripping will require other tools.
