An error in the table code:

1.1			1.2
2.1	2.2	2.3	2.4
	3.1
4.1

The table above is an example of a problem in the way this type of table is drawn by software (dreamweaver and browser):

Options:

1.) stretch the images to fit the improper cell heights (fill the 'gaps').

2.) make over and slice differently (surrendering to the quirks of the software: make a simpler table). More k on page.

first table: close all tags.
