Change Entry Header IMG, Remove default userpic border - SOLVED

[greekgeek13]

Newbie here. I've just started a new unpaid account LJ with Expressive Seasonal as the Theme.  I thought I'd able to override CSS by adding new CSS to Journal Display > Custom Options > Custom CSS, but I'm stuck already!

Problem #1) KILL SNOWMAN ICON
From this entry I pasted and modified the code

.asset-stream .asset-header-content {
    background-image: url(http://www.istad.org/store/teeny.jpg);
    width: 44px;
}
Problem #2) Kill black border around default user-pic in sidebar
Using a tip from this community, I pasted

.widget .user-pic img {
border: none;
}

Border is still there. I should be able to figure this out, but I'm stumped!
