Mouseover picture to text

I am now using this code in order to get text when holding over a picture in lighthouse.

<span class="tool_tip_link"><img src="[%GraphicsPath()%]arrow.jpg" alt="" border="0"></span>

<div class="tool_tip_text"> tekst info</div>

Is there someway to modify this, so that I can choose which pixels they work on? I have a picture with an info-boble in the upper right of the picture. And I only want the text to show if they move the mouseover to that info-sign. For example the rule could be like: only apply for pixels hight 730-749 and width 740-753.

Best,
