Two of my favorite tools for cleaning up after merging a dozen 
different home directories are FSlint and GQview. 

http://www.pixelbeat.org/fslint/
"FSlint is a utility to find and clean various forms of lint on a 
filesystem.  For example, one form of lint it finds is duplicate 
files.  It has both GUI and command line modes." 

http://gqview.sourceforge.net/
"an image browser that features single click access to view images and 
move around the directory tree 
 Features: Find duplicates based on file attributes or image content." 

GQview's duplicate finder is really nice.  Right-click on a directory 
name, select "Find duplicates recursive", set "Compare by" to 
"Similarity", and check the "Thumbnails" box.  Depending on how many 
images you have it might take a long time[1].  The end result is a 
list of similar images, where you might have both an original and 
retouched version.  You can also compare by checksum, which will find 
exact matches regardless of file name or location.  From the list you 
can select the copies you don't want to keep and delete them.

minutes on my new(ish) T61 laptop.
