Picture help

I am not computer illiterate, but I am not real great when it comes to these things either.   Most of what I know I learned by teaching myself, but I need some help.  How do I add pictures to my posts?  

Halloween

I am so excited that it is Halloween time.  It is my favorite holiday and a big deal in my family.  I have been to some haunted houses and hayrides and am going again tonight and 2 weeks from tonight as well.  I love that all the horror movies are on tv right now.  I even watch all the ones aimed at kids.  They're just fun.  I love passing out candy to all the little kids too.  This year my mom is bringing Tyler tutu to my house and we are all going to pass out candy.  She got him a football player costume.  I will post pics of him in the the costume.
