Subject:

Hattrick Organizer (HO) / Permission to display stadium images from arenadetails (v1.7)

Body:

Hello,

I’m a developer of the long-running CHPP application Hattrick Organizer (HO).

We would like to ask for permission to display the stadium image for the user by using the image URL(s) provided in the CHPP XML file “arenadetails” (version 1.7). The use case is our “Arena Sizer” feature, which shows the current stadium capacity and (if applicable) an expansion.

Our intended usage:

We will only request the image from the URL(s) provided by arenadetails (no crawling/scraping of any other pages).

The image is only shown to the user as part of the arena view in HO.

We will minimize load via caching and limiting the number of requests.

Could you please confirm whether this usage is permitted under the CHPP/HT rules?

Kind regards,
Sebastian Reddig (sgcr on GitHub)
