I am setting up a webdesign and the headers of the webpart titles is to be designed with an image which has bowed corners. The issue is that the webparts can have dynamical widths. I used FireBug to check how the webpart headers is constructed and found 2 TD on each side of the header
<tr class="ms-WPHeader"> <td align="left" class="ms-wpTdSpace"> ... <td align="left" class="ms-wpTdSpace"> </tr>
These 2 I can use to put in the bowed corners to make the rest of the headers background dynamical in width.
So - I wondered where I can find the file which constructs the "Default" Chrome Type?
