Images Alignment on Page problem. HELP

This is what it looks like in IE.



I've seen this before years ago, but I'm just now getting back into developing.
I've tried all I remember, things like "Left, Top, 0'ing out" all the images and Tables affiliated.

Note: I was able to align the Events Button snug, and also the Flower, but the other's won't go snug.
And here's where it can be looked at. http://www.leeuniverse.org/mission.html

Here's some code.

Thanks..... It's an emergency also. On a timeline.

 

Here's it up fully now.

This one someone else is helping me with, which still isn't correct.

This one is the original problem one with some of my own attempts at fixing.
The above code is what was originally there when I started this fun.
