It has been a while since I got my hands dirty writing code. So here is a tool I cooked up last night.
Share Quickly is a chrome extension which takes a screenshot of the active tab and uploads it to a public website which makes screenshot sharing a one click task. I plan to make these images disappear from cache after some time to save on storage... haven't figure out how to expose that yet.
The files are hosted on Google's App engine using cloud storage and the front end for that service is on Google Compute engine. I choose to write this in PHP instead.
Interestingly the backend storage is not limited to images only. You can actually use http://sharequickly.appspot.com/ to save and share arbitrary pieces text. Note that none of this is pretty, so be warned.
Feature requests and general comments are welcome.
