It's hard for any WYSIWYG editor to D&D any image into the correct spot. Your best bet is to position a table's columns exactly how you want it, I'll even create a hosting account and a make an HTML example for ya

But a good FREE editor is NVU, which operates on multiple platforms, and is open sourced. It is finally out of it's beta phases and at version 1.0

A good commercial editor is DreamWeaver, by Macromedia. I used to use this a while back, and I love it's interface.
