Size of the larger image is wrong

[NatoBoram]

I've done some testing and Discord limits the size of the image by 400px in width and 300px in height. However, when we select the image in the demo, we see in the CSS max-width: 520px;. It should be max-width: 400px; and max-height: 300px;.

Exhibit 1 :

Original image is 420 × 600 pixels.

Exhibit 2 :

Original image is 437 × 290 pixels.
