How to add an image
Say I wanted to add the image of a BF2 Cover, like the one seen to the right.
What I do is, I type in the following code on a new wiki-page.
[[Image:Battlefield_2_Cover.jpg]]
What will show up is a red link on the page. I then click that link and it takes me to an upload page. I click "Browse" and follow through until I find BF2_Cover.jpg, then I upload it.
Rut roh! BF2 Cover is 308 x 436 pixels large! That has to change obviously.
Thumbnails
To make a thumbnail image, which is far neater and organized than the large picture you see here. Simply type.
[[Image:Battlefield_2_Cover.jpg|Thumb]]
The addition of |thumb gives you a Wiki 150 x 100 pixel thumbnail.
Thumbnail Text
You can add text to the Wiki Thumbnail. For instance.
[[Image:Battlefield_2_Cover.jpg|thumb|This is BF2's cover]]
This will say "This is BF2's cover" in the wiki thumbnail text area underneath the thumbnail.
Resizing thumbnails
Obviously, one size doesn't always fit all. You'll notice this most likely when you are creating your very first Game-Wiki or Clan-Wiki. Often times we ask you to resize your thumbnails to make them fit in better with the pre-made spread sheet templates we've made for you to use.
For instance. We ask that everybody resize their Clan-Wiki image to 200 pixels. To do so, you simply type in:
[[Image:Battlefield_2_Cover.jpg|thumb|200px]]
After which it'll resize both dimensions automatically for you, without distorting the image.
