Ok - it took me a bit to get the hang of posting pics as well. The first thing that I didn't understand was that the pic needs to be somewhere else on the net, like uploaded on Flickr, for example. Once you load it there, you can right click the picture and go to porperties and then copy the URL to insert inbetween the "[IMG]" and the "[/IMG]". Now, for some reason that I do not know, not all images from my Flickr will display, so, sometimes I have to click the image and get a different URL (Even though it may be the same picture, just different URL).
Hope it helps.
PS - Here's a nice pic that I snapped in Michigan's Upper Peninsula:
The code looks something like - I replaced the [] with () so you can see the code:
