How to make the image control display high-resolution image？

I am modifying the Unity skin to display the song cover in the background (from the URL), but the display is always blurry. However, when I open the URL in my browser, the cover is actually high-definition. May I ask how to display images from URLs in its original resolution?

        <control type="image">
            <description>Artist</description>
            <aspectratio>scale</aspectratio>
            <left>0</left>
            <top>0</top>
            <width>100%</width>
            <height>100%</height>
            <texture background="true">https://p1.music.126.net/aJWtwvdYRXvKUpAE2C6NoA==/109951168919708423.jpg</texture>
            <visible>true</visible>
        </control>
