Bob,
you uploaded the pictures in the SandBox. You need to upload them on the page/group where you are adding the content, because SandBox content is for trials only and may be deleted.
So I moved them to the correct area, and used the correct Attach: commands.
When linking pictures from the forum, I usually scale them down so as to not make them too big on the page.
%lfloat width=500px% http://www.sl113.org/forums/uploaded/91lux/2006928131827_Filter%20%20pagode%202.JPG

The %lfloat width=500px% command says to align the picture to the left, and limit the width to 500 pixels. The [[<<]] makes sure that the text following the picture does not float to the right of it, but that the line returns back to the left.
The other thing I did was add structure to your content (Definition, Components, Maintenance etc)
