BB Code styles from Fireboard to Vbulletin differences causing code to show in post
 

I am working on an import from Joomla Fireboard to Vbulletin. This is one of several issues I am trouble shooting.

The additional shortcode options for "img" embed are causing the image shortcode to display and not show the image. In Fireboard you can do HTML Code:
[img size=150]url...[/img]
and it shows the image at that size. When I imported to vbulletin that broke the embed. I removed the "size=150" and it showed right up.

My question is if I have a very large site on Fireboard using the image size property for embeds, whats the best way to fix it? I thought I could copy over the shortcodes from Fireboard to my vbulletin, but upon update in the future it would overwrite that.

The site did not host images they specified people to use image hosting services so I need to keep that from breaking.

Your suggestions are greatly appreciated!

Thanks, Clayton
