Attaching pic's can be done 2 ways. One by clicking on the yellow Mountain and Sun box and putting in a URL for pic's that are on the web already. Also you can upload them directly to the post by hitting the "Go Advanced" button and then the "Manage Attachments" button and upload them directly from your computer. I have a Compressor, but no real ducumnets or info on them. Others have posted some info in the past. Rod
