How to attach a full sized image inline?

1. Put {img][/img} placeholders in your post where you want the images to appear.

2. Upload your images.

3. Preview your post. The image thumbnails will appear at the bottom of the preview.

4. For each image, right click on its thumbnail, and select "Copy link address" -- not "Copy image address."

5. Paste this address between the img tag placeholders from step 1. above.

That's all there is to it!
