Also there's photobucket (which I use), but it's all much the same thing - as long as you can link to a jpg file directly
(without all the hosting guf).
I had no idea you were trying to post images directly onto the TrekBBS - is that even possible? It certainly explains my confusion at your situation! At 137 posts to your name, you achieved the entitlement to include images in your posts some time ago. And I also would love to see your efforts. The more, the merrier!
