Hi Alan
I copied this from an old post a while ago, never tried but assume it works.
Adding Photos to a Post
You need to resize your photos to something like 800x600 or 1280x1024 pixels using a tool such as the free graphics tool IrfanView (on a PC as a Windows example).
Adding them, you need to upload them into your forum post (easiest from a desktop computer) via the Attach Files button - you can add a number this way, then once uploaded, place the cursor somewhere in your edit, and press the Attach File button and it will add a link into your post to the uploaded photo at the cursor position.
Cheers
