I am using BBCode [img] tag per the FAQ, but apparently I am doing it wrong...
Can I post images?
Yes, images can be shown in your posts. If the administrator has allowed attachments, you may be able to upload the image to the board. Otherwise, you must link to an image stored on a publicly accessible web server, e.g.
http://www.example.com/my-picture.gif. You cannot link to pictures stored on your own PC (unless it is a publicly accessible server) nor images stored behind authentication mechanisms, e.g. hotmail or yahoo mailboxes, password protected sites, etc. To display the image use the BBCode [img] tag.
I can finally post an image using the PB-Image tag. The FAQ is not very clear on how to post images.
OK after several trial and error attempts, it seems you can't use [img] tags with a PBase URL?? For that it seems you have to you [PB-Image] tag.
The URL for the picture below is not PBase and when I use [img] tag with it, it works. Jeeeez, go figure.
