just for the records: i made a huge step forward in rewriting robert's cool image_macro (here's the code in a cvs branch of antville, third function from top).

the features of thumbnail_macro() and imageurl_macro() are now included by handing over param.as = "thumbnail" or param.as = "url". well, to be honest, param.as = "popup" does the job of the thumbnail macro, while param.as = "thumbnail" does almost the same just without popping up a new window using javascript... (good?)

moreover, i started to modify some of the global renderSomething() functions: the problem was that they are hardly re-usable due to many res.writes in the code. so i renamed these functions to renderSomethingAsString() and replaced the direct output by building a string and returning it in the end. then, i added new functions with the old name as wrappers to directly write out the result of the --AsString() functions again. while it sounds complicated here, i think it becomes quite clear when you think of renderSkin and renderSkinAsString...

is that a way to go? would you support this code structure?
