New Image Tag e.g [imgo] for bigger images

[utw-Mephisto]

I know this has been discussed about a hundret times and believe, i have read them all.

BUT: I did not find any solution so hopefully someone is so kind and gives me an answer or a link where this might has been posted.

I have a small board (PHPKIT is like PHPBB) for our gaming clan.

I found a hack there where you have a second image tag.

Using [IMG] did not change, but when using [IMGO] it resizes images automaticly to 400xkeep_ratio

Is there anything like that for vBulletin ? And I am not talking about Avatare or Attachements

I am using 3.0.6 btw ...
