finder png to jpeg to iphoto makes creates multiple image files

Hello, Very first post on this forum.
My issue is that I used Automator to create a service to convert png files to jpeg files and import into iPhoto and to delete source file (After upgrading to Mavericks the old context commands were gone) . What has been happening is that after the context command has been performed, in Finder multiple jpeg files (5+) of same image begin to show up. I don't know what to do with them. I have been deleting them in Finder but the jpeg is then deleted from iPhoto. Any help on this?
Thanks

Hi again.
Is there any more information I need to provide for this issue. Or is this an issue at all. This is the link for the guide on converting png to jpeg if that helps. How To Add "Convert to JPG" To Mac's Context Menu - InformationWeek
Thanks in advance for your help.
