I've tried to use this module, to allow end user to have floated images and other Wysiwig subtilities.

I've configured an input format with this filter and the following syntax (copied from another post)

a[!href|target<_blank|title],
div[align<center?justify?left?right],
p[align<center?justify?left?right],
br,span,em,strong,cite,code,blockquote,ul,ol,li,dl,dt,dd,
img[!src|alt|title|style|width|height|margin-left|margin-right|margin-top|margin-bottom|float|class|typeof],
h2,h3,h4,h5,h6,
@[class|style|title]

I've tried a lot of thing, it doesn't work, the arguments are being stripped for <img style=""> or for <a target="_blank" > tags.
I've tried to keep only this filter (to prevent error from a combination of many filters)
I've tried with Tiny MCE instead of CKe EDITOR
No way, my images style"margin-left:20px " properties are being stripped.

What can I do ?
