bbPress.org

This CSS below did not increase the width and height of the photo:
#bbpress-forums div.bbp-reply-author img.avatar {
border: medium none;
max-width: 150px;
padding: 0px;
margin: 12px auto 0px;
float: none;
max-height: 150px;
}

This CSS increases the space between the photo and the post, but does not increase the size of the photo (does not increase the width and height of the photo):
#bbpress-forums div.bbp-forum-content,
#bbpress-forums div.bbp-reply-content,
#bbpress-forums div.bbp-topic-content {
margin-left: 150px;
padding: 12px 12px 12px 0;
text-align: left;
}

So I wish I could increase the size of the width and height of the picture, and also the space between the picture and the post.
