This info below might be useful to someone doing something similar, but just skip to the two questions below it if you like:

- - - - - -
I'm using Uncle Cheese's KickAssets module to add multiple Images to pages. Then I'm attempting to show them individually on the page with thumbnails and links to next/previous.

Using Kickassets the Photos are just files (as opposed to a new Dataobject)

static $many_many = array ( 
   'Photos' => 'File' 
   );

So I'm using the Datobjects as pages technique but instead of calling a data object I'm calling the File by its ID in the URL eg. /show/165
public function getPhoto() 
{ 
$Params = $this->getURLParams();

if(is_numeric($Params['ID']) && $Photo = DataObject::get_by_id('File', (int)$Params['ID'])) 
{ 
return $Photo; 
} 
}

This is working perfectly (after many failed attempts) - and in my template I can show the current photo using

<% control Photo %> 
<img src="$URL" alt="$Title" /> 
<% end_control %>

In order to show the thumbnails I call all the Photos belonging to this page:

public function ShowPhotos($limit = null) { 
   $data = $this->getManyManyComponents('Photos', '', 'ManyManySort', '', $limit); 
   return $data; 
   }

And on my template

<% control ShowPhotos %> 
<a href="$Top.URLSegment/show/$ID" id="$Top.Photo.ID"><img src="$URL" alt="$Title" /></a> 
<% end_control %>

So far so good (and the above might be useful to someone trying to do similar)

Question 1
- - - - - -
But I'd like to know how to highlight the current thumbnail, because $LinkingMode won't work for files … essentially I need to do this

<% if ID=Top.Photo.ID %>class=current<% end_if %>

but this doesn't work - so how would I write that as a function I can call from inside this ShowPhotos control loop?

- - - - - -
Question 2
- - - - - -
What's the best way to call the next and previous file links?

Any suggestions or advise on this would be greatly appreciated, thanks.
