This bug has been around for a long time, but actually, i can't find it in the bug archive:

When you embed multiple images in the OE, all of them with alignment "left", they will be shown side-by-side in the OE, with the following text displayed to the right of the last image (supposed, they are small enough)

When you publish the article, then the images are stacked on the left-hand border of the article and the text goes to the right of the top article.

So, in preview, they are in one line, after publishing , they are in one column.

This must be consistent!

This is the OE XML code

Bilder links 

<embed size="medium" align="left" offset="0" limit="5" href="ezobject://420" /><embed size="medium" align="left" offset="0" limit="5" href="ezobject://424" /><embed size="medium" align="left" offset="0" limit="5" href="ezobject://454" />Text goes here

Steps to reproduce

Note by ar: This is caused by the images being embed and not embed-inline, possible fix is to set clear: left / right in editor for these images so they behave like they will in templates / output.
