i think you just need the image URL. thought i've never tried. haha. there is an insert image icon in the "posting" area. click on it, insert the image and voila.
Right click on ur picture in fb and chose copy image location. Then in the forum click on the mountain insert image icon. Paste your location. It should end with .jpg. Remember copy image location, not just copy the url at the top of the browser.
Not too sure but i think if we ask politely then shouldnt be a problem as long as we dont get in thier way esp in the early mornings i think. I just happened to come across an empty one with a low door so i hopped over and shot some quickies hehehe. Hope to come bk when tide is high to do a few LE shots from the jetty side though...
