Resolved Help!: How to delete duplicates

[Black Chrome]

Hi, I am in need of saving some space on my Mac. I have noticed (especially with pictures) that there are a lot of duplicate everything in my hard drive.
The trouble that I'm having is sometimes when I try to delete pictures it says something about an original alis not being found; so I cant delete it.

Any help/tips on how to delete things would help, for I'm no computer wiz.
(I have a Mac OS X, with latest software 10.6.7)

Thanks!

Take a look at DiskInventory X, OmniDiskSweeper, JDisk Report or GrandPerspective to see where your HDD space went to.
And to delete duplicates: dupeGuru or FindDuplicateFiles.
