Yes, they interpret the HTML a bit differently but its the CSS that they
interpret much more differently.
Here's a list of differences in MSIE 6 and in Mozilla and Opera 8+:
MSIE 6:
CSS enhancements in MSIE 6:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnie60/html/cssenhancements.asp
Mozilla and Firefox:
Mozilla's Quirks Mode
http://developer.mozilla.org/en/docs/Mozilla's_Quirks_Mode
Mozilla Quirks Mode Behavior
http://developer.mozilla.org/en/docs/Mozilla_Quirks_Mode_Behavior
Opera 7 and 8 doctype switching:
http://www.opera.com/docs/specs/doctype/
When your webpage does not trigger quirks mode but instead trigger
standards compliant rendering mode, then there are just a few
differences and the rendering in modern browsers (browsers after 2001;
IE6, Opera 7+, Mozilla 1.x, Firefox 1.x, Safari 1.2+, etc.) their
rendering is much closer to the specs and more correct.
Sorry if that sounds a really dumb

No it's not; actually not enough people actually know that.
More on this (the table is a bit outdated):

Not sure if this is what you want but I think this is what I would use:
<p> <img src="[path]/filename.ext" width="..." height="..." alt=""
style="float: right; padding: 8px;">Big long paragraph of text</p>
