I upload pics straight from my PC into an album on OB. After uploading, I open a new document on my PC (usually Word). Then using the BB Code within the "album" here on the board, I copy/paste to my document.
Then, when I start my new thread, I just go to the doc, copy/paste to the thread. Using the "Go Advanced" setting.
For me it's the easiest way, because I'm not switching back and forth between websites.
