Evidently it's possible to use HTTP Caching for images, .css files, .js files, etc.  Since the site skin rarely changes, it seems like it would make sense to reduce the the number of request/response roundtrips by setting "max-age" for images (and possibly .css and .js) files.  Presumably, the client would just use the local copy and not even require a roundtrip...

Does anyone know how to do this in DNN?

I know there are some settings in IIS console:
for a specified images (js css) folder, Properties - HTTP Headers - check Enable content expiration, and set a big number of days.

The type of caching you are talking about is done automatically by your browser.

It doesn't do it when you are authenticated though because of headers sent by DotNetNuke to stop local caching in case a machine is shared.

DotNetNuke Modules from Snapsis.com

I think it's set by the page Cache-Control headers which the browser then uses to determine when to re-request - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/IETechCol/dnwebgen/IE_Fiddler2.asp, http://support.microsoft.com/default.aspx?scid=kb;en-us;323290, etc.  I see it's turned off in Default.aspx.vb.

What's interesting is to use Fiddler to look at www.yahoo.com or www.microsoft.com and note that every image, .js and .css file can have a different setting.  If it's controlled by the Page Cache-Control headers, how do they do this?
