Tile-Image in OpenGraph

1 Initial Problem

With ILIAS 9, the feature Improved presentation of ILIAS links in social media was introduced to improve the presentation of links to ILIAS pages in social media. a standard image (ILIAS logo) is displayed in each case.

2 Conceptual Summary

the tile image of an object - if available - should now be used when a link to an object is shared in social media. this means that no new masks are required in ILIAS where specific images are uploaded for this purpose. the image of a tile is used and delivered in a cropped version
