How copy albums from iPhoto to folder by using AppleScript

Ok. I made script which copy album architecure in to folder. Now i need copy images from iPhoto to folders and i don't know how do it correctly.

For example

tell application "iPhoto"

set sda to photos of sameAlbum

set lo to number of photos of sameAlbum

set theCommand to {}

repeat with n from 1 to lo

set paths to image path of item n of sda

tell application "Finder" to set currPath to POSIX path of "/Users/dariuszgardynski/Desktop/katalog"

--set theCommand to theCommand & ("cd " & currPath) & "; "

set theCommand to theCommand & "cp " & paths & " " & currPath & "; " as string

do shell scripttheCommand

end repeat

end tell

but paths have had recently spaces and shell crush.

Besides i prefer something like that:

tell application "Finder" to set currPath to make new folder in desktop with properties {name:"qwerty"}

duplicateitemn of sdatocurrPath

Can anyone help ??
