    [disc-art] => Array
        (
            [original] => upload/c/4/c4eea45ce0f5e8d5698f5ff2d18b4566.jpg
            [preview] => Array

            [original] => upload/7/2/72bb5a03708c99c822a792c76c00e8d1.jpg
            [preview] => Array

            [preview] => Array
                (
                    [dvd-insert] => upload/b/1/d_insert_b1f8e49d77121c01011acaa90cabc8ee.jpg

                    [boxshot] => upload/7/2/d_boxshot_72bb5a03708c99c822a792c76c00e8d1.jpg
                )

        )

)

I want to return an array that accesses each preview and gets the contents

array('dvd-disc' => '...path...', 'dvd-cover' => '...path...', etc...)

Please help, it has been a long day and I want to go home! :)

EDIT:

Correction - I want my final array to look like this...

array(
    'dvd-disc' => '<img src="'.$path.'" alt="'.$type.'" />',
    'dvd-cover' => '<img src="'.$path.'" alt="'.$type.'" />', 
    etc...
);

where $path is the value of each preview's sub-value and $type is the value of each preview's sub-key

"I want to go home!": You could still post what you have tried, or what your particular problem is ;) Don't you know how to access the elements? Or how to combine them? — Felix Kling

@Felix Kling Sorry, I have tried to accomplish the problem to no avail with foreach loops and array_push, but I can't seem to wrestle this one down. — Dave Kiss

$new_array = array();
foreach($main_array as $sub_array)
{
   if(isset($sub_array['preview']))
   {
       foreach($sub_array['preview'] as $type => $image_url)
       {
           $new_array[$type] = '<img src="'.$image_url.'" alt="'.$type.'" />';
       }
   }
}

Tim - you answered my original question, but my brain is fried and that actually wasn't what I was looking for. Should I ask a new question, or can you edit yours here?

@Dave: That should do it now.

// (the array you are bring in is $mainArray)

// New array we'll be creating
$previewPaths = array()

foreach ($mainArray as $item) {

    foreach ($item['preview'] as $previewName => $previewPath) {

        $previewPaths[$previewName] = '<img src="'.$previewPath.'" alt="'.$previewName.'" />',;

    }

}
