You can cut and past its code line, e.g http://somethingsomewhere.jpg
between image tags like and [*/img] . There is no '*' , I had to put that so the tags remain, and dont try to post 'and' as an image.
Alternately, some image storage places online like photobucket etc give you a code after you upload an image there, complete with tags, you just cut and paste into the post.
If you click the 'Go Advanced' button below (when your posting) it gives you an option of uploading images too. Look for the paperclip button.
Normal posting gives you this button to add pics [img]https://www.chameleonforums.com/images/editor/insertimage.gif
