I just wanted a way to quickly share an image on IRC (or some IM, or even twitter) without the need to register or login.
I wanted a site that wasn't cluttered with "recent photos" or comments and likes and what not. When I shared (or received) an image I wanted to do just that, show an image to someone, on a clean uncluttered page via a shortened URL.
I didn't want to make any kind of albums or do any kind of image organizing. I wanted to post it, and then forget about it and let the image expire automatically after 24 hours.
Basically I wanted a Pastebin but for images. Hence, Pixbin. :) Hope you enjoy it.
