Is there a way to shorten this code?

I'm creating a site which has a series of boolean fields to control what icons are displayed on a page.. in total there will be around 20 fields for this particular section.

In my template I have something like this:

<% if Field1 %>
   <img src="$ThemeDir/images/icon/Field1.jpg" title="SField1" alt="$Field1" width="32" height="32"/>
<% end_if %>
<% if Field2 %>
   <img src="$ThemeDir/images/icon/Field2.jpg" title="SField2" alt="$Field2" width="32" height="32"/>
<% end_if %>
<% if Field3 %>
   <img src="$ThemeDir/images/icon/Field3.jpg" title="SField3" alt="$Field3" width="32" height="32"/>
<% end_if %>
<% if Field4 %>
   <img src="$ThemeDir/images/icon/Field4.jpg" title="SField4" alt="$Field4" width="32" height="32"/>
<% end_if %>

Can that be re-rwriiten to something shorter?

I've realised that the alt tags and title tags in that won't work, eg they will just display "1" values.

Would still be interested if there was a way to reduce the code?

Group all the fields into 1 DataObject set via a PHP function. Something like

function FieldsForPage() {
$output = new DataObjectSet();

for($i = 1; $i < 10; $i++) {
$field = "Field$i";
if($this->$field) $output->push(new ArrayData(array('Field' => $this->$field)));
return $output;

<% control FieldsForPage %>
<img src="$ThemeDir/images/icon/$Field.jpg" title="$Field" alt="$Field" width="32" height="32"/>
<% end_control %>
