print icon disappeared?

[mbp]

Hello!

 

I use PrestaShop™ 1.4.5.1

 

How do I remove the "More Information" button?

 

I do not understand why my print icon has disappeared?

 

I have the icon in the right folder, 100% that it is right

 

I use this CSS code to modify the icons:

 

#usefull_link_block {

list-style-type:none;

margin-top: 20px

}

#usefull_link_block li {padding:2px 0;}

#usefull_link_block .print {

padding-left:20px;

background:url(../img/icon/print.gif) no-repeat 0 0;

}

#usefull_link_block li.sendtofriend {

padding-left:20px;

background:url(../img/icon/send_friend.gif) no-repeat 0 0;

}

#usefull_link_block li#left_share_fb{

padding-left:20px;

background:url(../img/icon/picto_fb.png) no-repeat 0 0;

}
