Upload a picture of your choosing - not of yourself, of someone who looks funny. Might I suggest chris-chan? Or http://encyclopediadramatica.com is always a good source for images - NSFW.
Wait - this will take about 5 or 10 minutes, I suggest you browse the web in the meantime. It plays a loop until it gets to you, but it's worth the wait for the satisfaction of having your picture judged live. It'll 'buffer' - ie: skip our of the loop - before and after your picture, so you'll hear silence before your picture is judged. Be ready for this.
An option offering to share a video of your review will appear after your picture has been approved and judged. Link to this - we'll all be able to see what you see.
