POSTING A LINK TO AN IMAGE FILE OR INSERTING AN IMAGE INTO A POST
Get an account at Photobucket.com (or some equivalent host) and upload the images from your computer (or camera directly) to there. Then copy and paste either the Url link to the image file or the Img reference itself to a post. Both the Img link and the Url link are generated under the image on photobucket.com by that site automatically. Here's a couple of examples:
If I post the following link, you only see the link in the post, clicking on it will allow you to download the linked image from photobucket.com:
http://i16.photobucket.com/albums/b8/rogersb/i1010.gif
If I post the IMG link (as below), then I will have the actual image inserted into the post, as long as I don't break the link by moving the image file on photobucket.com. If you do, you have to update the links to that file or you only see a placeholder, no image any more.
