So... If I want to post a linked image of my pet to it's profile... how do I go about doing that???

Click the IMG= button above the comment box, and in the window that pops up, insert the URL of the page you want to link to. Then click ok, and it will generate a code like this:

[ img=URL OF PAGE ] [ /img ]

Then insert the URL of the image you want to use between the brackets, like this:

[ img=URL OF PAGE ]URL OF IMAGE[ /img ]

And then you're done!
