Ok to start you have to reduce your pictures to 600 pixels or less, I use picsizer, download it, it is the ezest 1: http://www.axiomx.com/picsizer.htm
Then to post them go to Post Reply and lower on the page you will see add attachments go to browse
and find you picture file and click open
after that click Add the file
them wait a couple of seconds and it should post. You can do at 3 pictures in 1 reply, I have seen ppl have more but I don't know how they did it. If you need more help pm me.
