from no HMAC_salt timestamp... comment out line 112 or 89 on other version

Without any image input everything on this page, here

To create the AWS s3 signature as above.
NO IMAGE YET SUBMITTED .

TRY NOW , PLEASE

^^^Copy this as, awss3payload.png , and use it for testing.
Use EXIF to see signature

In this website you encode a string you want to decode... try SGVsbG8 decodes to Hello http://base64-encoder-online.waraxe.us/

There are no aws secret keys within this PHP script, and no aws keys needed for this script :)

This site creates secret hash that AWS machine recreates to then accept users commands.
For general public use do not use any secret key value pairs in forms.
