Hi Pc,
Thanks for your comment, your way is another solution too, the software which i linked can dedect duplicated pics even theyre flipped or rotated, so i dont like dup pics in my archive so im deleting the one which is smaller in size.
For your way you can use a software like "SuperCat" for cataloging zips, this software can also search in cd's or DVD's, shows you whats in without putting CD in CD-Rom. Have a nice day,
P.S. Have a look at deviantart.com theyve a great pic archive, not releated about hair pics but theyve great pic organizng systm. over 15.000.000 pics.. about art.
