Here the guide how to upload screenshot in forum.
1. Go to www.imageshack.us or www.photobucket.com
(imageshack is easier to use). Here I used imageshack image hosting.
2. In there browse the picture that you want to upload it.
3. After choose the picture click button 'host it!
4. After host finish it it will be like this.
5. Copy the url which said 'Hotlink for forums (1)" which show like in
picture below.
6. Preview your your post before send it...
7. After you satisfied.....Send it.....
Now your screenshot done and have been shown at forum.......
Signiture Picture you can make by using this guide also...
But for Avatar Picture Forum you only need to copy the url begin with "http://" and ended with ".jpg".....No Need to copy the whole url like in my guide above for Avatar Picture Forum...
I hope this guide will help you guys for making a great screenshot.....
That's all.....Thank You....
