If I post a pic with every post will I make more money  

posting a pic might help but it does not mean that you get earnings for every picture

you get more for the more you do. That is what participation mean. If you post a picture with each topic yes it does mean that it will help a little however, you will want to post quality data on each one of your posts. This post you will get little credit for because 1) there are not a lot of responses 2) if what you posted was a reply it would be really short and not listed as quality content. When you post make sure that your replys are 4 lines long or longer. Then you will start making the big bucks =D

Happy mylotting and good luck!
