Edit in User Album Page

Hello,

The user album page looks like:

Attachment 130438

I want to reduce the height and width of the outer box as indicated by the red arrow and notice that in Firebug the definition of css - class"picture" for the same as:

.picture {
display: block;
height: 608px;
padding: 10px;
width: 608px;
}
and I want to reduce the width and height to 208px. So defined it as in additonal.css:

.picture {
height: 208px;
width: 208px;
}

but I do not see any changes effected. But in Firebug when I edit these values to 208 px the effect is visible.

Notice the red arrow pointing the change in css definitions.
Let me know how to make this change in css.

Thanks.
