Could you please post the library ID?

Missing legacy boxart for "A Plague Tale".

Library ID: 1901367087

I don't know how. Can you tell me?
Thank you

A Plague Tale: Innocence needs a Legacy Image GOG ID: 1924096256

It's a new game, so just mentioned that, because I've finally got round to the one, I've never had a legacy Image for.
Cyberpunk: 2077

Surprising as that is, obtaining the GOG ID may show why, there is two ID's listed

GOG Database gives these details
Cyberpunk 2077
Product ID: 2093619782
Slug: cyberpunk_2077
Product Type: Package
Access: Unlisted
Supported Sytems: N/A

Cyberpunk 2077
Product ID: 1373464609
Slug: cyberpunk_2077
Product Type: Package
Access: Private
Supported Sytems : N/A

However using Pale Moon v28.7.2 (64-bit) Dev Tools Inspector (Using "Inspect Element" context menu entry)
On my Games Library page, I get completely different product ID's for both games.
While games I actually have legacy Images for, the ones I checked, all seem to match the GOG Database ID's

Cyberpunk 2077
gog-account-product="1423049311"

A Plague Tale: Innocence
gog-account-product="1901367087"

Anyway here's a good Image for A Plague Tale: Innocence
A Plague Tale - Innocence - Cover.PNG

I think the yellow cyberpunk Image used by GOG/CDPR is awful, here's an alternate, but there's not much to choose from yet
Cyberpunk 2077 - Cover.PNG

Both pics are 500 × 700 Pixels, which is the right ratio, for images, as far as I can tell.

Just go to Manual Sort and click on "Export Sort Oder". This will copy the actual sort order into the clipboard. Now open notepad or edit or whatever and paste from clipboard. You will see something like this:

"{"1901367087":{"id":1901367087,"name":"A Plague Tale: Innocence","sortBy":0},"1290147220":{"id":1290147220,"name":"Fenimore Fillmore: 3 Skulls of the Toltecs","sortBy":1},"1104118179":{"id":1104118179,"name":"15 Days","sortBy":2}"

The library ID is the one that's listed behind "id". So in the example above:
A Plague Tale: Innocence = 1901367087
Fennimore Filmore: 3 Skulls od the Toltecs: 1290147220
15 Days = 1104118179

I just fixed A Plague Tale: Innocence with the image you provided. Thank you.
Also changed the Cyberpunk pic - but I don't own the game so let me know if it worked :)

Yes, those games that are missing legacy covers seem to be those that show different IDs in ProductID shown by GOGDB and library ID shown by your browser (or by the method I described above). I will contact Johny from GOG and will try to ask him if this problem can get fixed for future releases.

Edit: Here's Johny's reply

"API that will be maintained and should work best is Games V2 API - api.gog.com/v2/games<ID_HERE>
This one is extracted into your library: 1901367087
This one is the store element: 1924096256
and the one from library have an image in the API: images.gog.com/10426b33fb6a31774a3fe82203697375b3b135571e0fdb5fd48b6c7130bfca76.png"

And he is right. The boxartimage of Plague Tale was in the API ... AF just did not show it for whatever reason.

Thank you HypersomniacLive. With the cover provided by UhuruNUru I already fixed Plague Tale.

export sort order button does nothing (nothing in the clipboard) both on opera and on firefox. Not sure if this is a system language problem or just something that only work on chrome.
Got this error on the console:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON dataeval line 3 > Function:1098:32

On opera:
Uncaught SyntaxError: Unexpected token u in JSON at position 0
at JSON.parse (<anonymous>)
at HTMLInputElement.exportManualSorting (eval at buildCode (account:1), <anonymous>:1097:32)
at HTMLInputElement.dispatch (eval at buildCode (account:1), <anonymous>:4:8066)
at HTMLInputElement.r.handle (eval at buildCode (account:1), <anonymous>:4:4767)
at HTMLInputElement.f._rollbar_wrapped.f._rollbar_wrapped (jsGlobal-9196dde.js:1)

Try the way UhuruNUru used:
1) In your library click on game.
2) In context menu (right mouse) click on "Inspect Element" - it will open an additionmal window.
3) In the search field enter "gog-account-product" and start the search.
4) The number shown here should be the correct product ID.

I added a screenshot for the example of Plague Tale.

Just to confirm, I'm now seeing both A Plague Tale, and Cyberpunk images.

So we can't always rely on the ID's from GOG Database, but using the Developer Console's Element Inspector, will always be correct, because it shows what your Library is currently using.

That seems to be the case, yes.
And thank you for the confirmation.

Ok for Asterix&Obelix XXL3 should be
gog-account-product="1621135703"

Should be fixed. Can you please confirm?
