The portraits come from two places, and the terms differ. That is why they are listed separately below rather than in one list.
Free images come from Wikimedia Commons and are used under a free licence. They are cropped and scaled to thumbnails and otherwise unchanged. The photographer, the licence and the original file are given with every image. That is the condition for showing it, not a courtesy.
Embedded images are Svensk Elitfotboll's own player portraits, fetched straight from allsvenskan.se when you load the page. They are not freely licensed and are not copied here. They are shown from Svensk Elitfotboll's server, and the rights are theirs. The copyright in every such image belongs to Svensk Elitfotboll. The pictures were taken by Bildbyrån, as Svensk Elitfotboll told us themselves. Svensk Elitfotboll has given the go-ahead to embed them here, and to nothing more.
This page covers all six football games: England Edition, Topp 5, Allsvenskan, Djurgården, AIK and Hammarby. If a picture is shown in any of them, its photographer is credited here; a picture the games share is credited once.
Topp 5's squads, who plays for which club, come from English Wikipedia (CC BY-SA 4.0): the leagues' tables and the clubs' own articles. The player facts come from dcaribou/transfermarkt-datasets (CC0-1.0) and, for players missing there, from Wikidata (CC0), the geography from mledoze/countries (ODbL), the Allsvenskan squads from Fantasy Allsvenskan, and the squads, spells and appearance figures of Djurgården, AIK and Hammarby from Swedish Wikipedia (CC BY-SA 4.0), its season articles and the players' own articles. England Edition's squads and player facts come from the same English Wikipedia, Wikidata and transfermarkt-datasets, linked to each other with Reep (CC0).
