module not fitting correct-very urgent

Hi
Please see
jedac.org i have installed this module here
now the left white space is something i wanted to get rid of so i resized the pics but you see the module is not starting from the left instead from the right though the module position is left in the template.
if i increase width of the module then it goes to the right side so my site gets bigger to the right i increased the size so that the space gets filled up on the left
whats wrong with this module?

Hi,
In template.css (line 42) you defined width for all modules to 280px. To override this, you can add class:
.moduletable_slider with different width. Then add "_slider" in module class suffix parameter of the Hot Image Slider module.

so I need to add a class this way
..moduletable_slider{width:600}

where exactly do I need to insert this code which line?

okay i have sorted it out placed the code right thanks a lot
