I found out myself. There's important information missing in
Post 52. If you defined the phrases as global phrases (which seemed the appropriate way to me since there was no specific phrasetype mentioned to define them in) and want the phrases to show up, you must do the following:
FIND
Code:
function handle_bbcode_img_match($link)
{
ADD AFTER
Then the phrases will show up.
For further information please consult
this chapter of the vB manual
