how do I parse the first [img] tag from a post and show its thumb on showthread?

[dannylin3000]

I'd like to show a thumb of each thread on my showthread.

Is there anyone know how to show a thumb of the first images posted using [ img ] from each thread?

I wish to have an answer for this too .-)

Interested in a solution for this, too.
