Ok, so I have seen requests by members on how to post pics here on the forum. I'll be honest, I only know how to do it for a MAC but you may be able to get the jist of it from here and work it out for a Windows system.
Step 1) find a pic you would like to post. It can be either one already online or one you have on your computer. If it is on your computer pay close attention to step 2.
Step 2) It must be posted online somewhere (as you need an address for it) to make it work. I have an account with BGG where I gallery all of my pics that I would like to post here. ask around and forum members will offer other sites that will host galleries for you. Upload your computer pic and get an address for it.
Step 3) Click on the green "Image' square in the bar of icons in the post window.
(this green square icon)
Step 4) Paste image adress into the field and press enter. Your pic should show up in the window.
Hope this helps you out.
