You can post photos as "attachments" to a post (not the best way).  The better way is to use an off-site image hosting company (I put stuff on my own webserver) and then link to it here...you just input the URL in the photo popup and it will insert it for you.

Thanks Matt. It took a while to figure out, but here's a photo of the male with eggs in his mouth.
 
This is the female.
