center image does not work with size tags from images

[OuttaSpaceTime]

Hi,

Thanks for the great plugin!
I have a custom css that centers all my images:

img
{
	display: block !important;
	margin-left: auto !important;
	margin-right: auto !important;
}

so quite simple and straight forward. I notice that it seems to cause troubles with your plugin.

So my question is do you have an idea how I can get both working?
And the other might be a feature request to handle the center, left align, right align etc with an tag as well.
maybe something like [#center](image path)

Would love to see that one!

Thanks in advance
