I'm working on an interface layout in Photoshop that is approx 2500 pixels wide (I like to work big

. I have it all done and the slices made. When I move it to Imageready, of course it stays 2500 pixels wide.
Now, when I go to save in Imageready, there is no option to resize the image like when you use 'Save for Web' in photoshop.
I've tried to resize the image in photoshop before moving to imageready, but it seems to loose some small details and quality that aren't lost when you 'save for web' and resize.
Any suggestions??
