[RESOLVED] 50%alpha, onRollOver+onRelease=100%alpha

Perfect! Thank you very much for that.

For anyone who is interested: to prevent the thumbnail from being clicked again (if already selected) add the following:

target.onRelease = function() {
      if (this != picked) {      //added
             callFullImage(this._name);
	     picked._alpha = 100;
	     picked = this;
      }  //added
};
