Twitter icon displays full column width

My Twitter tweets are displaying a giant profile image which fills the width of the column, instead of the usual thumbnail icon image floated left. How do I make this work so it shows the icon?
Joomla 3.5.1, Social Stream 1.2.1.

Thanks!

Dear Jose Roman.

Thanks for your reply, Huyen Tran!

I modified the following code to have a 40px width and height and it seems to have fixed the problem.

.stream li.dcsns-twitter .section-thumb img {
width: 40px !important;
height: 40px !important;
float: left;
}

Note that we also have changed the following style to have a 100% width, which was probably causing the problem:

.stream li .section-thumb img {
border: none !important;
padding: 0px !important;
background: #fff;
width: 100%;
}
