There is no built-in functionality for exporting to images. Generally, though, if you are using the non-flash charts (ie, not AnnotatedTimelines, GeoMaps, or MotionCharts), and your data sets are reasonably small (not 1000's of data points), there are no performance issues when rendering multiple charts. I have some pages that render upwards of 30 charts with no issues, but YMMV. I'd give it a try and see how well it works before looking into harder solutions.
