Image Alignment Issue

When I insert an Article using this feature http://awesomescreenshot.com/05f5yu9o25
the image aligment looks fine, but when i send it as preview the images are not aligned in any email client. I found that it is because images are missing inline css to align them. This is a bug. I believe all image should be aligned by sendpress editor in a way, it can be supported by all email clients. This is a pretty basic thing a newsletter editor should have in it. Can you please check ?
