Some people don't know how to take pictures without a screenshot, so I'm going to show you how.
First, you'll need a keyboard. There are different types of keyboards, so I'll give you two pictures.
Anyways, find the button that has the letters "Prt Scr" over the letters "SysRq"
Once you press the button, it'll take a picture. Make sure you don't press it more than once, unless you feel you didn't get the picture right.
The Prt Scr button should be inside of these red squares. If not, look for it.
Once you've pressed Prt Scr, open Paint. If you don't know what I'm talking about, It's icon will look similar to this one.
(I use Windows XP, so it may look a little different on other types of computers)
So, once you've opened paint, go to the menu at the top and click on edit, and then find the paste option. If it isn't clickable, you didn't press Prt Scr. You can also type Ctrl+V to paste it quicker.
If you've done it right, you should get a picture of your whole desktop. Crop out the unneeded areas of your picture.
Okay, well you're not done yet. You still have to post the picture on the forums! Go to image shack, photobucket, or any website that can upload photos. If you don't have an account for photobucket or image shack, register.
(I used Photobucket)
That IMG Code down there is what you need to see the picture, you need to copy and paste it onto the forums. It'll look like a lot of letters, but it works.
P.S: If it doesn't work, the Direct Link works just as fine. Copy and paste the link and post it for each photo you get.
That's the guide for now, and if you have any questions, feel free to ask.
