How do I download a copy of the art that appears when, in the Steam client, I click a card in the "[Account] earned a trading card" section of a Library page for a game?
And it seems if I've earned a card too far in the past, I can't see the image anymore, and that only that section of the client reveals an image.
Not sure how steamcardexchange managed to find the URLs for all the images, when they click on them.
On chrome: Left click on the image, inspect element: There should be something with a background image closeby. Its the image you are looking for.
Here is the URL for the image you talked about. https://cdn.cloudflare.steamstatic.com/steamcommunity/public/images/items/960690/db70016d6b4eb82fb30fa7a33f4fa202ef2b36da.jpg
Other solution, CTRL+S will save the page locally, with everything related to it. The image you are looking for should be in all those files.
But yeah, uf you are looking for an automated way to get the image, I would guess the https://steamcommunity.com/dev has what you are looking for. I just don't know enough to guide you in it.
