If using a mobile device or tablet, the slickest way to post pics is with TinyPic. It embeds a key on your device's on screen keyboard. Hit that key (it looks like a globe) and a menu containing all the recent images on your device appears. Select the photo(s) that you want posted. TinyPic uploads the selected pics to the TinyPic server for hosting and inserts a link into the thread reply text box. Hit the submit button on the thread's reply menu and done.
