Dumb Stupid Dumb Idiotic Pop Ups!

Nutscrape on the other hand is absolute rubbish IMO and I've found Mozilla to be merely marginally better.

If you're talking about NS / Mozilla behaviour, you have to mention the versions. NS 4x is like 8 years old, Mozilla 1.3b just a few weeks. Of course there's different behaviour.

About your example w/ the pic: Mozilla (or whatever you were using for the screenshot) does exactly what's in the code: There's three pictures (the warrior, the logo, the barb) in a table row, they don't fit next to one another once the browser window gets too small, so Moz performes a line break, so all pics will be displayed fully. IE however treats them a some sort of layers, which they aren't, and stacks them when the browser window gets small- and then starts to mess up the following text (links) like this (IE v6):



There's a number of possibilities to construct the code in a correct fashion that will display the LL header as intended and with all browsers, but I won't get into that - it's not my site ;)

Not to mention having a 3 pixel margin added to the bottom of every image

You could use this opportunity to find out more about the difference between block elements and inline elements, and their behaviour in "strict" mode, when there's a specific W3C-URL in the document type definition.
(Short version: As long as you define the pic as an inline element, those pixels will be there, as a block element they won't, or if you just don't use a URL in the DTD. This behavior is correct, and will probably be adapted by a future version of IE. I don't know if Opera does it yet - they will in any case.)

60% - 80% of Nutscrape bugs repeated in Mozilla

You should really check your Mozilla version - everything from Version 1.0 has next to no rendering bugs - a lot less than any other browser there is to date. Maybe you're still using an early alpha version (typically v0.8x or something)
If there's anything to really criticise about Mozilla, it's the speed, but that's another issue.
