Is there a way to check image files for duplicates before uploading?

For example, with Ponibooru you could search by MD5, and I used this in a script to check for dupes before checking out artist name and the like.

We use SHA-512, here. Try searching sha512_hash:<checksum>

But be aware that we perform image optimization here, so you may not get the results you want without running the same optimizations yourself. All of them except JPG optimization are lossless but will obviously affect the checksum.

Maybe you should start storing the original hash as well, to help with this.

Hash: SHA1

We are now doing this (to fix our own issues with exact dedupe so for
more recent images we can provide this. We'll be exposing it in the API
soon. Images without an original hash stored (before approx 120000
id_number) will have a nil value for the original hash key.

Cheers,
Clover
