Reproducing the Issue
Within a group in SAP users can upload images in various areas (content, feeds, overview page etc.) There is nothing within a group that states a recommneded resolution.
From a practicality perspective, users should upload the largest image they have available.
- In reality there is no benefit in uploading an image over 1920 x1080 (HD wide) as the SAP Jam UI (user interface) doesn't go that wide.
- The widest users can go in any usage scenario anywhere in SAP Jam is roughly 1200px on an overview page, if the area has 1 container in a row (and SAP Jam will resize the image to fit the space where the user inserts it) and 800px in a wiki or blog.
