Having trouble finding an image source? Post it here and see if anons recognize it. But first, try using these reverse image searches: https://saucenao.com https://fluffle.xyz/ https://iqdb.org https://ascii2d.net https://trace.moe https://yandex.com/images https://images.google.com https://www.tineye.com Still can't find it because it was probably uploaded to Twitter? Try searching the image signature if it has one. Yandex can also read text on images even if it's in Japanese. Useful if you can't read a signature in moon. (If the signature is sloppy and a search isn't getting results, you may need to try different spellings.) Can you read the signatures on these images? I couldn't until someone else told me they were taitai and yus-ts respectively. You can always md5 search various boorus, but usually SauceNAO would find them if they were uploaded there.
