STEP 1. PrintScreen.
During battle or reviewing battle, press "PrintScreen" button on your computer (usually up-right corner of your keyboard) to take a picture from the battle. STEP 2. PAINT
Open a picture drawing software, the easiest one (I am using) is Window's Paint (Start --> Program --> Accessories --> Paint).
And paste your printscreen picture into it. Edit it a little bit and save as .jpeg file on your computer.
STEP 3. POST
When you make a thread or reply one in our forum, attach the picture as a file.
Then in your post, right click on the file and copy the address of the file.
Then Edit your post again, and click on the "img" button, paste in the file address. and save it.
Finally, you can see a post like this with pictures. :)
