ASP.NET Resource resx String tooltip display help

I have a string, Mini-move.Help, stored in a resource file that I would like displayed whenever user clicks on the help image that is displayed.

NOTE: the help image is displayed dynamically when you add the .HELP to your resource string.

I want to style this display in such a way that when user clicks on the image button generated as a result of storing the resx file, a popup/toolt开发者_运维百科ip like popup shows up instead.

Every Few Minutes - MM:
<br />Every Hour - H; <br />
Every Day - D;Su,Mo,Tu,We,Th,Fr,Sa;<br />

How do I accomplish this please?

thanks in advance

<img src="[path]"  title="" onclick="this.setAttribute('title', '<%$ Resources:SiteResources,Mini-move.Help %>');" />

This will set title on image when click event occures
