I disagree. You should be practicing accessible, progressive  
enhancement. The first example does have a URI, it's the relative  
path to Waldorf-Astoria-Photo.html and should be set up to work from  
a spider, script disabled browser, or even a "right-click to open  
link in new tab." Your practice of wiring javascript to a button is  
effectively hijacking the user's browser will do nothing except  
ensure the content is inaccessible to all but a few targeted user  

<a href="Waldorf-Astoria-Photo.html" class="ahah-photo">photo</a>

Works as a regular link and–once the right event handlers are  
assigned–will work as a JS-enhanced interface.
