Code to display clickable tumbnails

Hi,

Need simple code to display inside the item page (not the listing page) a tumbnail of the image and beneath it, the title of the image. The tumbnail should also be clickable so when a site visitor clicks on the image it will display the full image.

Also, I need the code to display somthing if there is no images associated with the listing. Somthing like "no image available".

Any help will be greatly apreciated.

The code I got from the HTML code genetator follows.

<!-- STEP 2a: Display Uploads for field 'images' (Paste this anywhere inside STEP2 to display uploads) -->
<!-- Upload Fields: num, createdTime, tableName, fieldName, recordNum, preSaveTempId, filePath, filename, extension, thumbFilePath, isImage, hasThumbnail, urlPath, width, height, thumbUrlPath, thumbWidth, thumbHeight, info1, info2, info3, info4, info5 -->
<?php foreach ($minyanRecord['images'] as $upload): ?>
<?php if ($upload['hasThumbnail']): ?>
<img src="<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" alt='' /><br/>

<?php elseif ($upload['isImage']): ?>
<img src="<?php echo $upload['urlPath'] ?>" width="<?php echo $upload['width'] ?>" height="<?php echo $upload['height'] ?>" alt='' /><br/>

<?php else: ?>
<a href="<?php echo $upload['urlPath'] ?>">Download <?php echo $upload['filename'] ?></a><br/>

<?php endif ?>
<?php endforeach ?>
<!-- STEP2a: /Display Uploads -->
