is there a way to achieve this effect in a cross-browser compatible way without having to prepare separated images?
Basically the frame on which text lays has a white overlay of 50% opacity.. I would like a solution that doesn't involve creating any other image in addition to the background but I don't know if it's possible!

Try RGBA, e.g.
div { background-color: rgba(255, 255, 255, 0.5); }
As always, this won't work in every single browser ever written.
If you can't use rgba due to browser support, and you don't want to include a semi-transparent white PNG, you will have to create two positioned elements. One for the white box, with opacity, and one for the overlaid text, solid.
body { background: red; }
.box { position: relative; z-index: 1; }
.box .back {
position: absolute; z-index: 1;
top: 0; left: 0; width: 100%; height: 100%;
background: white; opacity: 0.75;
}
.box .text { position: relative; z-index: 2; }
body.browser-ie8 .box .back { filter: alpha(opacity=75); }<!--[if lt IE 9]><body class="browser-ie8"><![endif]-->
<!--[if gte IE 9]><!--><body><!--<![endif]-->
<div class="box">
<div class="back"></div>
<div class="text">
