I seem to recall that BBCODE image tags (just like HTML tags) support the dynamic resizing of images. All that's required is the addition of two additional keywords & associated values in the image tag itself.
The regular IMG BBCODE tag goes something like this (minus the dots at the start & end):
Code:

To dynamically resize an image, the BBCODE tag should goe something like this (minus the dots at the start & end):
Code:
[.img width=100 height=100]https://teakdoor.com/images/smilies/dtroll.jpg[/img.]
But for some reason the second example doesn't work here
However it does work at the Ajarn etc.
