Rooster#3- If you find an image online that you want to post here, all you do is simply copy the url of the image, paste it into a BYC post, highlight it, and then click the "Img" button (which is next to the smiley faces and the Bold, Italic, Underline, etc...) The "Img" should wrap around the image's url. Then, post and it should show up.
BTW, make sure when you choose a picture, that you "view the image" (right-click and click 'View Image") Then copy the url to THAT page where you view the image.
