Thanks for the suggestion, but that didn't work. Something about the image resizer code is causing the height and width to be blank. If I remove these 2 lines of code, the height and width are displayed.
<?php
if(TRUE){ // Begin Cached Resized Image: ImageCacheInstance_1287416098580
ob_start();
?>
<?php
echo(getCachedResizedImageHTML(ob_get_clean(), "image_cache", "fit", "#FFFFFF", false));
} // End Cached Resized Image: ImageCacheInstance_1287416098580
?>
