Topic: Search for this image
Find or compare files can match images.
Sometimes i'm looking for similar images as the one i'm looking at.
In a way you can do this now by searching for image *.jpg and check Image in Find identical files, then look for the file you want and see the matching ones.
An easier way would be something like: Search for "this" image.
I don't know how to compare images so i can't write it myself so i leave it up to you what you think of it.
