Duplicates?

Is there no way for me to check similar/dup? I don't want to upload an image already posted. I've tried using "find similar" button but it direct me to danbooru. Do I have to hope that my uploaded image is not a dup?

It took some digging but the Find Similar button on the uploads page should now hit http://3dbooru.iqdb.hanyuu.net/ now instead of the Danbooru version like the find similar link does on a post show page.

Keep in mind that hanyuu.net is a third party site so if it goes down all I can do is shrug and say welp.

hey thanx mate
