yup, i was about to say that... ;p
It's good for light use, like i do... batch resizing, rename....

you could also try the XYplorer, it's a nice, complete (and a little complex) Win explorer replacement... but it's paid... (you can use a limited trial)

Thanks, Drakhyrr! Tonight I'll put it to the test.

Any other option, mates? :)

More suggestions, please?

So far, no ideal program for the task, although Visipics and Anti-Twin are close to what I'm looking for.

If only they had a full screen comparison mode (so that you could change the view between an image and its duplicate to detect small differences between them) and a more user-friendly way to rename or move out pics!

As for Beyond Compare & FastStone, they only compare a single picture against another (and you must provide the path to both images).

BUMP!

Any last suggestion? ;)

Since the last entry, I've been testing some programs. I leave here the results, hope they serve to help someone with the same problem.

TL;DR: The best among the tested in the list below would be Awesome Duplicate Photo Finder, FirmTools Duplicate Photo Finder or even Img Search.

Still looking for the ideal program... :)

---

The folder used for the tests was a directory with 975 pictures (mostly color illustrations, with a percentage of 5% in B&W illustrations and sketches), scanned repeatedly by other programs (Visipics & Anti-Twin) until they found no more similarities.

Awesome Duplicate Photo Finder
- found 227 similar groups with 454 images (without a single false positive)
- very fast / almost no configuration options

Detwinner (trial version)
- with 80% sensitivity, 69 groups with 147 found similar images (8 false positives: B&W drawings)
- no options to rename or move, just delete, list of results very unfriendly
- trial limited to 1000 images

DupKiller
- scans only whole logical drives --> not tested.

Duplicate Cleaner Free
- free version has no image search --> not tested.

Duplicate Images Finder
- very slow and strong use of CPU --> not tested.
- consist only on a small window that lets you choose the directory to scan

FirmTools Duplicate Photo Finder
- found 98 groups with 198 similar images (without a single false positive)
- no rename option, trial version can't move or delete the duplicates found
- very fast

Image Deduplicator
- found only one group with 2 similar images
- half translated into English, the rest in German

Img Search
- 2002 program with Windows 95 interface (uses the PC speaker to beep when it find a duplicate)
- with 85% sensitivity (default) found 80 groups with 168 similar images (one false positive)
- with 75% sensitivity found 89 groups with 190 similar images (13 false positives)

Picture Relate
- took a long time to read the directory, but is quick to search it
- allows to change the sensitivity and search again on the fly (without repeating the directory reading)
- option to compare the images found in full screen
- 12 groups of 2-3 images each, other group with many false positives (over 50 B&W drawings)

Similar Images
- groups of similar images presented consecutively, rather than a list of all them
- with a threshold of 35% (default) found 20 groups with 40 similar images (3 false positives: B & W drawings-)

Interesting to read. So, what would be your freeware recommendation so far which I can bookmark now and later recommend others to steal all the credits ;-)

Very nice your research thesp, maybe i'll bookmark and use it later... ;p


edit: hey! But not with the same purpose of NukeDukem... o/

Undoubtedly, Awesome Duplicate Photo Finder :D

See above. ;)

Always a pleasure to make business with you, but I'm sorry, I have to leave now...

Nah, thanks for testing and sharing the knowledge. Always interesting to read such comparison tests.

I have no experience with your query other than to suggest alternativeto.net; if you haven't already.

Thanks for the reply, Porkdish!

In fact, it was through alternativeto.net how I found the programs listed above. :)

Who would have thought that I would be so difficult to find a software that met my expectations!
