The way this works is first, you log into Jokeroo. If you don't have an account, making one is easy and free. Of course, if you want to get paid, you'll have to have PayPal or some method of receiving the money digitally, so you'll want to connect your PayPal account to your Jokeroo account too.
It turns out most of the things I've taken pictures of are of Firion, and not many funny things. Heck, I barely saw myself in my photos either, so I haven't found a worthy picture to put for my profile image on Jokeroo. But these are some of the things that I did have that I found to be funny. The first one, I've already written about in this blog post, but I updated it a bit by turning it into a Demotivational Poster.
I should try to see if I can get a funny picture of Firion or something, as soon as I get what I want... >_<
Edit (9/23/2013): Ultimately, I gave up on the site. I wasn't able to cash out what "money" I was able to accumulate. The link to the site has been removed from the Cool places list.
