You may already know imgur, an image host you can use freely for whatever you please.
An interesting fact about them, however, is that each picture given a name consisting of only 5 alphanumerical characters. This leaves for roughly 916 million different names. As it turns out, there appears to be around 90 million uploaded images, which means that if we randomly guess a name for a file, we have an about 1 in 10 chance of actually finding an image.
Those odds are pretty good, so I wrote a small application which does just that.
It’s written in F#, so you’ll need the F# Runtime 2.0 installed for the program to run, but apart from that it requires no installation: Simply run the .exe-file to use the program.
Credit goes to whomever wrote this script for inspiring me to create an improved version.
Enjoy finding random strange images!
