I think this is the easiest way to post pics...
1) Click on Go Advanced button on the bottom of this page
2) Scroll down to Addtional Options on the new page you get after step 1
3) Click Manage Attachements, which would pop up a small window.
4) And you can upload the pics by...
a) clicking on Browse
b) select the right pic from your computer
c) repeat a and b for more pics (You can only do 5 at once)
d) click on Upload when you are done and wait few secs till you see Current Attachements showing up in that window
e) click on Close this window
5) Click on Submit Reply in the larger Purse Forum window and voila~
