Resizing Linked Images

I've been tasked with the challenge of re-sizing images linked via BBcode on the fly. I have compiled a list of functions that do individual components of this task, but stringing them together has proved, well, a challenge.

I discovered this code that will re-size the images, however this will need to be added on an ad-hoc basis, and the fact that the image name appears twice complicates the usual system I used to add the code.

Usual way of replacing the code (inside a function):

Code:

vText = Replace(vText,"[ img ]","<div align='center'><img align='middle' src='")
vText = Replace(vText,"[/ img ]","'></div>")
