Find you a hosting site to upload your photo's to. I use my web space from my internet provider and I also use www.hunt101.com. If you use hunt101.com upload your photos then copy and paste their location in your posts using , place the location in between the brackets with no spaces.
Once your picture is uploaded to hunt101.com, click on it then "copy and Paste" using the example below. "Right" click on image link, click copy and go back to your intended post and type [img], right click again just to the right of " at the end.



I hope this helps..
