umm, it is really easy. just add 'padding-direction:Xpx;' in the cd tag. Replace direction by 'top, bottom, left, right' and X by the amount of pixels you wanna pad your pic by. ;]
For example,
YOLO
code: [cd*=width:50px;height:50px;background-color:white;][COLOR*="Black"]YOLO[/COLOR][/cd]
And padded version
YOLO
with code:
[cd*=width:50px;height:50px;background-color:white;][COLOR*="Black"][cd*=padding-left:11px;padding-top:16px;]YOLO[/cd][/COLOR][/cd]
Hope that helped a bit. =p
