I ran the cropped picture through a Bing reverse image search, and got a slightly larger version that was rotated 90°. I then ran that one, and ended up with a much larger version that I simply rotated to the same orientation as in the product photos.
The image is 4096 x 2731, so you should be able to resize and crop it to the FW’s resolution.
EDIT : hmm, it looks like the forum only allows up to 1920 x 1280. Okay, I guess I’ll try to link the image itself. You’ll have to rotate it 90° clockwise, but that shouldn’t be too difficult.
I really like the 12th gen wallpaper too, but as it has a lot of detail regarding the symmetry of the lines it’s probably not crop-able? - Would also love it if framework posted the original images for them!
