Find random images from http://i.imgur.com/ Imgur is a free image hosting service. Many people use it. Here is an example of an imgur link: http://i.imgur.com/T55muMD.png. Write a program that continually outputs random (valid) imgur links. For example, here is some sample output of my progam (not shown because it contains some tricks you will have to figure out yourself):

Helpful hints:


When imgur was new, 5-letter links were used.
When imgur was new, numbers weren't used.
You can use this to your advantage: only find 5-letter link images with only letters. That is what my program does.
Also, all images are saved as .png.


Requirements:


Continually output random imgur links
Links considered sufficiently "random" if 50 are outputted with no repeats
When visited, links must be an image
Links must start with http://i.imgur.com/ and end with .png
Score is amount of characters


I did it in Java (TERRIBLE for golfing) in 452 chars. Not shown here because it contains some tricks you will have to figure out for yourself!)
HTML (152)

&lt;img src=x
onload=console.log(s);g()
onerror=g=function(){s='http://i.imgur.com/'+Math.random().toString(36).substr(2,6)+'.png';event.target.src=s};g()&gt;


This logs all found images on the JavaScript console using console.log(). Works in all tested browsers (Firefox, Chrome, IE9, Safari and Opera).

The fun part is that all sorts of funny images are flashing up for the blink of an eye :).

Try it! (jsFiddle wraps this into a more complete HTML page, but browsers also accept the single element.)

Props to the amazing random string method by doubletap!

Where can I see the JavaScript console and the logged images?


Firefox: Press Control-Shift-K (Command-Option-K on the Mac). Unselect the Net, CSS and JS buttons there, only select the Logging button.
Opera: Press Control+Shift+i, select the Console tab.
Chrome: Press Control+Shift+i, select the Console tab. On the bottom, select Logs.
Safari: Basically like Chrome, but make sure first that Safari's developer tools are activated. Then press Control+Alt+C (on Windows, not sure on the Mac) instead of Control+Shift+i, select the Console tab. On the bottom, select Logs.
IE: Press F12, select the console tab.
