1) what version of zencart are you using, because the version of image handler being used (from what i can tell from the js file), is at least 2 or 3 years out of date if not older, you should be using Image Handler 3 on a modern site, especially as the old js doesn't work correctly in Opera, Chrome, Safari, IE9
The image IS there, or at least the code appears to be, It looks like someone had a go at altering the Image handler code badly if i am reading it right
I went to this page here
http://californiacoldsaw.com/cart/in...ndex&cPath=9_5
clicked on the first product
http://californiacoldsaw.com/cart/in...&products_id=6
now look at the source code
HTML Code:
<!--bof Main Product Image -->
<div id="productMainImage" class="centeredContent back">
<script language="javascript" type="text/javascript"><!--
document.write('<a href="javascript:popupWindow(\'http://californiacoldsaw.com/cart/index.php?main_page=popup_image&pID=6\')"><img src="bmz_cache/6/63b7ac08c19e81a85c39ab597da17f46.image.147x120.jpg" alt="Lenox CycleHD Coolant - 1 Gallon Bottle" title=" Lenox CycleHD Coolant - 1 Gallon Bottle " width="147" height="120" style="position:relative" onmouseover="showtrail('bmz_cache/c/ceaafe47b6a8594f1c70e74b9af99b1e.image.368x300.jpg','Lenox CycleHD Coolant - 1 Gallon Bottle',147,120,368,300,this,0,0,147,120);" onmouseout="hidetrail();" /><br /><span class="imgLink">larger image</span></a>');

</div><!--eof Main Product Image-->
Those images are on the server, but the code there is Borked, it looks like they have tried to put the hover effect on to the main image, (which was a fairly shaky hack in the very old version and has since been dropped), Anyway this is the code from the site I linked to earlier
HTML Code:
<!--bof Main Product Image -->
<div id="productMainImage" class="centeredContent back">
<script language="javascript" type="text/javascript"><!--
document.write('<a href="javascript:popupWindow(\'http://sweetbrucies.co.nz/index.php?main_page=popup_image&pID=45\')"><img src="bmz_cache/2/283b856abb6c5a26027efa3ec52a4f9b.image.89x120.jpg" alt="Dragon Sweets - Assorted Creams 2kg Bulk" title=" Dragon Sweets - Assorted Creams 2kg Bulk " width="89" height="120" /><br /><span class="imgLink">larger image</span></a>');

Something not right with your code
edit------------------------------------------
the script and noscript tags in the "Main Product Image" div are both showing up as "display: none;" when i view them in Dragonfly
