Need software to compare pictures to find duplicates.
I have about 800 wallpaper pictures that I collected from different
sites. When I view them I occasionally see the same picture twice. I
know there are some duplicates, because different sites change the
names of them. Aside from manually trying to find them using
thumbnail images, is there some sort of software (prefer freeware)
that I can download that will find duplicates based on the file size
or the actual content of the .jpg image, even of the names are
different? Most are the same screen size, so they should be identical
except for the name. One site even has duplicates on their site,
which are the same picture with different names. Not to mention I had
to rename many of them, because how many times can a picture be called
(for example), "dog.jpg". Generally how I cope with those, as I save
them, I'll rename them either as dog1.jpg, dog2.jpg, dog3.jpg ......
OR something like collie-dog.jpg. dog-poodle.jpg, black-dog.jpg,
dog_with_toys.jpg, etc.....

Maybe not the fastest program in the world, but it works pretty good. It's
been a *long* time since I ran Win9x, but IIRC DupDetector works just fine
there.
(I've got 4600+ wallpapers. Never ran DD against *that* directory, but... on
my computer (1GHz Athlon, 7200RPM drive) DD indexed 800 1600x1200 images in a
bit under 9 minutes... but YMMV. No, your mileage *will* vary.)

The best duplicate image finder I've come across is Duplicate Image
Finder (DIF), from Runningman Software:
http://www.rmsft.com/dif/screenshots.html. It compares images of
different formats and sizes, and you can set the percentage similarity.
The trial period should suffice for you. It definitely used to run on
'98 - you can still get a version that definitely mentions '98, at
http://download.cnet.com/Duplicate-Image-Finder/3000-2193_4-10056392.html
, though I don't know if that's the latest that does; Runningman
themselves only mention back to Me on http://www.rmsft.com/support.html,
though both mention the same version number.
But from what you say, you're probably only looking at .jpg files, of
the same size - i. e. quite possibly identical files (though not if of
different compression qualities). For general duplicate file finders,
I'd recommend http://www.satsignal.eu/software/disk.html#FindDuplicates
which is from the site of the chap who wrote it, or EasyCleaner, from
http://personal.inet.fi/business/toniarts/ecleane.htm, which includes
the same code as part of a nice suite (originally stolen by the suite
writer, though unknowingly, and he and the original coder are friends
now). Both of these must be rubbish, of course, since the download files
are quite small ... (-:

webpages is whether it compares images of different sizes, though I
think it will.

I went there; I was just making sure it still existed.)

aspect ratio (within a given percentage of difference), select from 4
different methods to compare by, tell it to use one particular method (not
choosable) if one image is b&w, etc. It's a *very* good program.

Looks like it does everything Duplicate Image Finder does, except for
free - apart from (from the screenshot, anyway) showing you the
pathnames of the two images for matches it's found.

Sounds like it! I shall definitely try it on one of my image archives.

No, it only shows the filename below the image -- but it *does* show the path

in the list above the thumbnails. I've never considered that a minus, myself.
