You need to upload your photos to some sort of online hosting. Some use
www.flickr.com, some use
http://imageshack.us/.
Then you need to post it using vb code, which is just attaching [img ]http://to the front of the web address for you picture and [/img ] to the end (without the extra spaces, of course). Most image hosts will give you the correct form for posting your image on a forum already prepared with the image tags.
Example: [img ]www.mortalenema.com/images/LittleSpecialAvatar.jpg[/img]
I left a space in the first image tag so you can see the text.
Without the extra space you get:
This should get stickied for everyone.
