[Feedback] Inner BBcodes

Here is a BBCode tryout post i made to test PunBB for the first time, The code i posted there is used to imagelinking as you know.
Even imageshack.us uses that kind of linking for its uploaded images.
The code pattern is simply

[ url=link_here][ img]image_adress_here[ /img][ /url]

here is the post:

I wanted you to notice and wodered if it may be fixed with a hotfix or later release of PunBB
