Graphic size browser window smartphone

[TWiegand]

Hello, I have another question.
A graphic with 500x500 pixels is also 500x500 pixels on the desktop computer in the browser window.
On the smartphone, however, it is much larger compared to the resolution. With a display resolution of
1440 pixels high, the graphic is higher than the visible area, i.e. higher than 1440 pixels.
