Missing pictures for some games

I think it is another thing connected to steam api and it takes pictures directly from steam, which would mean it isn't possible add them from sg side.

All of those are complete (...) editions that do not have a picture on Steam (at least I think so).

all except for monkey island are packages of some special / deluxe edition.
some of them dont even have a valid steam page (anymore)... though i hope its not just me being in germany
packages usually dont have a picture

dont know whats up with monkey island though... maybe oppenheimer is right about some "normal/not sold as package" special editions not haveing pictures as well

I'm not sure which Steam API SG is using, but there is an API which returns game info for games/packages as JSON, which includes header/capsule images if available:

• https://store.steampowered.com/api/appdetails?appids=32460
• https://store.steampowered.com/api/packagedetails?packageids=92163

You can also directly plug the app/sub ID in these urls and see if steam returns a header image:

• https://cdn.cloudflare.steamstatic.com/steam/apps/32460/header.jpg
• https://cdn.cloudflare.steamstatic.com/steam/subs/92163/header.jpg

(I believe steam has two interchangeable CDN prefixes for these assets: cloudflare and akamai)

Of interest is the monkey island game, perhaps SG cached the JSON response and the image was added sometimes after that (it didn't exist before)... According to SteamDB, the images were only added 2 years ago: https://steamdb.info/app/32460/history/?changeid=U:26593825, while the game app is much older than that (11 years?)
