Futurama Fry

Need a little more information please. Are you talking about memes you have made? Or are you talking about having memes that are in your personal area so you can easily use them to make comments with?

Ones I made

When memes are submitted, people at imgflip (mods?) views it and makes a decision as to if it can be featured. Once it is featured it becomes part of your profile. Unless it is downvoted back to submitted. Most downvoted memes attack one group or another and you can expect those groups to downvote.
