Your browser's -imageBrowser:itemAtIndex: data source method returns objects that conform to the IKImageBrowserItem informal protocol. You can specify -imageRepresentationType to return IKImageBrowserNSImageRepresentationType and have -imageRepresentation return a reasonably-sized thumbnail image.
If you manage a thumbnail cache to supply those images, you could restrict the maximum memory footprint and reduce the likelihood that you'll keep getting expensive (time-wise) delays trying to generate/draw an image in the browser.
