bianli(Server.MapPath("/")+"\pic")

InStrRev("abcd.jpg", ".") 计算出abcd.jpg中第一次出现.所在的位置是第几个字符=5

mid("abcd.jpg",1,4) 取前四位abcd

mid("abcd.jpg",5) 从五位往后取（包括第五位） .jpg

取前缀abc

FullPath = "abc.jpg"
f = mid(FullPath,1,InStrRev(FullPath, ".")-1)
Response.Write f

娶后缀jpg

FullPath = "abc.jpg"
f = mid(FullPath,InStrRev(FullPath, ".")+1)
Response.Write f
