Am not a tecno fan,but i just resolved this issue so i decided to share it,a boy brought me his
Tecno p5 saying that he added a an image/picture on his music
player background and don't know how to remove/change
it,so as the nature of my field as you know (WEBMASTER) I just
clicked music,then the next step is music menu then click "info"
from the display/list option and click on the box at the top right
hand-side of the song property
the click on the "Album/image" and select "Remove/Change".thats all.
