Get attachments from posts/pages

hi to the community,

i’m building a gallery using wordpress and i try to get all images included in a page,
so i have build an admin options page and from there i get the pages in a drop down and i have a problem filtering the content,

i use this code to get the images,

// Get the post ID
$galleryID = $artdev_get_gallery1;

// Get images for this post
$arrImages =& get_children(‘post_type=attachment&post_mime_type= image&post_parent=’ . $galleryID );

// If images exist for this page
if($arrImages) {

// Get array keys representing attached image numbers
$arrKeys = array_keys($arrImages);

// Get image attachments
foreach ($arrKeys as $iNum) {

// Get the thumbnail url for the attachment
$sThumbUrl = wp_get_attachment_thumb_url($iNum);

// Build the <img> string
$sImgString = ‘<img src=”‘ . $sThumbUrl . ‘” width=”150″ height=”140″ alt=”image-alt” />’;

// Print the image
echo $sImgString;
}
}

but i can’t filter the $artdev_get_gallery1 (is the drop down – page slug) to get the images from the selected page, it gets all the images from posts and pages also,
if i change the drop-down (to the admin area) to a text area and write the page id as a number i can filter the content.

i think that this is something simple but my knowledge is “newbie” and i can’t figure out how to do this.

if anyone have a solution on this i will be very thankful,

thanks a lot,
Philip
