Actcherly ... I don't think center/re is an available option on RPoL ?
FAQ (General RPoL Information | RuBB Code Tips & Tricks | Images) says left or right only:
quote:
The image tag will also accept the alignment attribute to move an image to the left or right side of the post (the code would look like this: <img src="http://beta.rpol.net/images/banner-light-beta.gif" align="right">). Note that vertical alignment options are not possible in RuBB code at this time, nor are other HTML image attributes available.
I tested in my game and both left and right work, but centre or center don't.
Could you put in a 3 column table and put the image in the centre cell ?
