Most use Photobucket to post pics, But there are better alternatives if you ask me.. IMGUR is one of them. I use facebook mostly. Just go to the pic you want to post.. Right mouse click on the pic and choose "copy image address".. go back to the post you want the pic at and right mouse click, Choose "paste" Then right below the "B" [bold icon] you will see a "insert image" icon. Highlight the pic address, then click on the "insert image" icon. Before you post you can preview your post to see if the pic showed up... If everything looks right, click on "post"..
Much easier to do then to write out lol
