Submitting photos
Firstly the picture needs to be taken from the internet or you need to upload it yourself. You can upload by for instance getting a photobook like photobucket or imageshack. Once you've uploaded your photo you find the direct link of the picture, an address that starts with http:// and ends with .jpg.
Copy that adress. Or if the picture comes from somewhere else on the web, copy the adress of that image.
Then make a post on the forum. To edit in your picture you click the Img button. Clicking that button automatically writes [ img ][ /img],if you cant find the button get glasses or type it yourself (without spaces in it). You glue in your address [ img ]http://...something....jpg[ /img] and submit/preview and voila, you have an image in your post.
Linking from words or images
Instead of writing the full address you might sometimes want a word or an image to be the link to another page. For instance wowhead or
.You do this by clicking the URL button. Clicking that button automatically writes [ url][ /url] (without spaces, you can type it yourself if you cant find the button). In between the two brackets you write the smiley or the word or picture you want to be the link. In the first bracket you add a = and then the address of the page you want the link to go to, like this: [url=http://www.wowhead.com/].
