, I'll tell ya the way I post images... it's quite simple.
Go to http://imageshack.us/
and upload an image file. Once that's uploaded, the next screen that shows up has several links which you can choose from. Choose the "Forum" link and highlight it, copy it, and paste it into the Reply box you type into to make a reply post here on TrekBBS. That's it. When you post it you get the image you uploaded as an inline image in your TrekBBS post. Nothing to it.
