The photo needs to be hosted somewhere on the web, such as at Picasa. The following will work with just about any photo on the web. For example, I did it with the Axiom logo above, which is nothing more than a photo, and got this:
In order to get the photo to appear in your post, you simply find the url of the photo itself by right clicking the photo and then clicking "Properties." In the small Properties window that pops up, copy the "address" to your clipboard.
In this case the address is
http://lh5.ggpht.com/_XIiHWyawKlo/SdtRf2VmQZI/AAAAAAAADu4/Ys8y8XAt3q0/s640/IMG_3473.jpg - the url must end with a photo designation, i.e .jpg, .bmp, .gif, etc.).
Then paste the url into the Axiom posting form and surround it with image tags ([img] and [/img]) it should look like the following only without the spaces. There should be no spaces in the entire chain.
[img]

If I eliminate the spaces, I get this which, by the way, looks TERRIFIC!!!! Nice job!
