In order to post a picture in your posts, you need to follow these three easy steps:

1) Resize your photo and save it as a JPG.
- If your picture is too big (ie larger than 640x480 pixels) it will take too long for everyone to download and it won't fit on most people's screens.
- If you don't already have photo editing software, there's an excellent freeware utility called Easy Thumbnails that couldn't be any easier to use.

2) Host the photo on a webserver.
- If your internet service provider doesn't include web space, use Imageshack. There's no registration required and it's ridiculously easy.

3) Link to the photo in your post.
- You can either use the insert image button in the Post New Thread window or you can use IMG tags in your post like this:

That's it!
