各位大虾：
            本人刚接触钣金，一些操作还不太熟悉，请问，下面的图例（林Sir书中的例子）如何展开？
           谢谢！

            <img src="attachments/dvbbs/2003991454072590.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2003991454072590.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
