No, It is Immpossible. I suggest you set the title property using javascript. For this you need:
1) Add a JavaScript element to the element. For example, the css or id class 2) get the element through the hook and set its name
Example:
document.getElementById("myImage").title = myArray[5];
<img id="myImage" src="_info.gif" height="26" width="37"/>
You can also use some JavaScript library like jQuery or Prototype
