Need help with Classical Chinese I'm a postcrosser and deltiologist. A few days ago, I received a postcard from China. There was some Chinese text along with the artwork on the front side of the card:



I tried the Google Instant Translate and this was the result I received:



So I asked the sender, whether he could translate it for me. And he told me that he is able to read it but don't know the meaning since it is written in Classical Chinese! 


Could someone tell me the meaning of what's written there?
the post card is a replication of a painting, which is in the palace museum (故宫博物院). imo, the quality is, unacceptable. here's a better image of the painting:



about the text, traditionally, one read from top to bottom, right to left. so, the rightest text are:


南刻京喬
宋畫口柯
諸之山急
公跡樓澗
皆為待唐
拜之風解
牀一觀元
下變六有
　洗如此
惲其卷景
壽勾筆因
平砍墨倣
　煥靈其
　然逸意
　神李　
　明唐　
　當　　
　使　　


it was written by the painter 惲壽平, as a "preface". the meaning of it, roughly is:


  喬柯急澗


tall and bent (喬) branch [of tree] (柯), torrential (急) stream (澗)

used as the subject of the painting.


  唐解元有此景因倣其意


"解元", "六如居士" were referred to 唐寅, a painter of ming dynasty.

誰不籦嶰
識經籠壑
馬裁潄臨
融作趾急
才笛哀澗
