Please, please if you are doing any Photoshop work for customer, do not export it with Photoshop's built-in engine. Few things: 1) table layout is sooo 90s and it's so fucking hard to fix if something brokes don't.. did I mention it doesn't scale unless you plan it real good and 2) absolute positioning.. well, that doesn't work well either in many cases.
Just use PS's slice tool to isolate all the parts you need like backgrounds etc. and then whip up a nice and fast loading div & css layout. It doesn't take much time but when you realize how it should be done, those layouts can scretch, bend, scale, minimize and basically work in every browser.
Sorry for the rant.. I have had my share of fixed table layouts in this life..
