Header slideshow widget size adjustments

Hi,
I’m using Suffusion theme and I added a Meteor Slides widget in my header widget area for a rotating slideshow and the initial settings were 525 or 550 width and 250 height but I’ve been trying to change that SS to 600 W x 250 L so I resized pics for the new SS, created a new SS, put in my CSS in the back end of Suffusion for the new size, deleted the old SS pics from the SS panel, deleted original widget and added a new one and put in the new SS slug and I’m still getting old information in code and I can’t figure out why or where it’s coming from. This is an example of the code I’m seeing in firebug:
<div class=”mslide mslide-1″ style=”position: absolute; top: 0px; left: 0px; display: none; z-index: 16; opacity: 0; width: 600px; height: 250px;”><img width=”525″ height=”250″ title=”F/T American No. 1 – Fishermen’s Finest, Inc. 600×250″ alt=”F/T American No. 1 – Fishermen’s Finest, Inc.” class=”attachment-featured-slide wp-post-image” src=”http://alaskaseafoodcooperative.org/WP/wp-content/uploads/AN1-600×250-525×250.jpg”&gt; </div>

The <img width=”525″ should be “600” and the “……uploads/AN1-600×250-525×250.jpg” should be uploads/AN1-600×250.jpg”

Thanks in advance for any suggestions or help
