How to stop auto-refresh onclick from thumbnails?
I have an image gallery on my site that uses thumbnails that enlarge above the thumbnail line when clicked on. I'm having an issue with the auto-refresh; every time I click one of the thumbnails, the page refreshes, which restores it to the "master image". 

I'm not (and sort of refuse, on the grounds that I believe all this can be done with simple CSS and HTML) using anything fancy to write this code, despite my knowledge of HTML being amateur at best.

Here's a sample of the code. Let me know if you need to see a different piece of it.

    <div id="rightcol"> 

    <img name="ImageOnly. src='#' /><img src="#" />
    </div>
    
    
    <div id="leftcol"> <div>
    
    <a href="" onclick="ImageOnly.src='#'"><img src="#" />
    </div>
