Rectangle{
id:rect
    property bool cond:true;
    Row{
     Image{ source:"good.png" }
     if(cond) {
         Image{ source:"good.png" }
         Image{ source:"good.png" }
     }
    }
}

Your code is syntactically wrong: QML structure description statements cannot be wrapped in javascript code.

But the solution is simple:

import QtQuick 1.1

Rectangle {
    id:rect
    property bool cond: true;
    Row{
        Image{ source:"good1.png" }

        // show image elements only if 'cond' is true
        Image{ source:"good2.png"; visible: cond }
        Image{ source:"good3.png"; visible: cond }
    }
}

Alternatively you can create the image elements dynamically, but this is more complex.
