Newbie question on styles inside html doc

hello,
I just try to setup a html based internet site and to make the element 
positions I decided to use tables. It worked all fine but than I wanted 
to make a background image for one of the cells. I first make the image 
in Paint Shop than insert it to the page. After it I changed it from 
normal picture insert to the backgrund through

<td
style="background: transparent url(./Bilder/Strichbild_Haus_klein.jpg) 
repeat scroll 0% 50%; -moz-background-clip: initial; 
-moz-background-origin: initial; -moz-background-inline-policy: initial; 
height: 150px; width: 200px;"
align="undefined" valign="undefined"><br>

(Don't look at the name, it's german). It worked too and I'm able to 
insert additional parts in front of it. But the size settings are 
strange. As one can see the cell size is 200 in width. The image size is 
200px in width too. But in the cell a small part of another instance of 
the picture is shown at the right-most edge of the cell, just two or 
three px in width. It looks ****y of course. I think it belongs to the 
repeat setting in the style-line but I don't know how to change it. Can 
anyone help me doing it?
