One that blows up similar to the forums proper or other sites and boards where it blurs/darkens the background and takes up the bulk of the screen with the image?
Can't really be done, and for the sake of maintaining some kind of ease of use of the site it probably never will be.

One that when clicked on takes you to another place, said place being the big picture? Trivially. You have the standard bbcode in there so it would be something like
Edit code thing is broken in ask, change the { for [ and } for ]
{url= http://somesite.com/mybigpicture.jpg }{img} http://somesite.com/mysmallsignaturepicture.jpg {/img}{/url}
