I made an AGPL-3.0 project in Python3 that fills in missing regions of images.
Someone made a website that uses the AGPL code on their server. A user uploads an image on their website, the image is saved to a folder on their server, and, the AGPL Python3 code (which processes the image) is executed with a PHP script.
They share their modifications to the AGPL Python3 code but do not share the PHP script or any other server/website code.
Is sharing the modified AGPL Python3 code sufficient? If not, what needs to be done to comply with AGPL?
