   Hi guys

   i have a problem in buliding query

   problem :it shows post image and default image

   i want to show post image if not available, default image
   i have placed the code and function for thumbnail which i used

   code

   <div class="newssection">
   					<div class="heading">
   						<h3>Latest Posts in <a href="'.$cat_link.'" title="'.$cat_name.'">'.$cat_name.'</a> category</h3>
   						<div class="clear"></div>
   					</div>
   							global $post;
   							$myposts = get_posts("numberposts=1&category=$cat_number");
   							foreach($myposts as $post)
   								{
   									$posttitle = get_the_title();
   									$posttime = get_the_time('F jS, Y');
   									$postauthor = get_the_author();
   									$postlink = get_permalink();
   									$text = get_the_excerpt();
   									$text = substr($text , 0, 150);
   									$nothumb = get_bloginfo('template_directory');
   									 $thumb = dp_attachment_image($post->ID, "Thumbnail", true);  
   
   									echo '<div class="article">';
   										echo '<div class="left">';
   											echo '<img src="';
   												if ($thumb == NULL) { echo ''.$nothumb.'/images/defaultthumb.jpg'; } else { echo $thumb; }
   											echo '" alt="'.$posttitle.'" />';
   											echo $posttime.'<br />';
   											echo $postauthor;
   										echo '</div>';

   function for thumb

   # Displays post image attachment (sizes: thumbnail, medium, full)
   function dp_attachment_image($postid=0, $size='thumbnail', $attributes='') {
   	if ($postid<1) $postid = get_the_ID();
   	if ($images = get_children(array(
   		'post_parent' => $postid,
   		'post_type' => 'attachment',
   		'numberposts' => 1,
   		'post_mime_type' => 'image',)))
   		foreach($images as $image) {
   			$attachment=wp_get_attachment_image_src($image->ID, $size);
   			?><img src="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> /><?php
   		}
   }

   Try changing this line:

   if ($thumb == NULL) { echo ''.$nothumb.'/images/defaultthumb.jpg'; } else { echo $thumb; }

   To this:

   if (! $thumb) { echo ' ' . $nothumb . '/images/defaultthumb.jpg'; } else { echo $thumb; }

   One more thing to change, in your dp_attachment_image() function. Change:

   if ($images = get_children(array(
   		'post_parent' => $postid,
   		'post_type' => 'attachment',
   		'numberposts' => 1,
   		'post_mime_type' => 'image',)))
   		foreach($images as $image) {
   			$attachment=wp_get_attachment_image_src($image->ID, $size);
   			?><img src="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> /><?php
   		}
   }

   To this:

   $images = get_children(array(
   		'post_parent' => $postid,
   		'post_type' => 'attachment',
   		'numberposts' => 1,
   		'post_mime_type' => 'image'));
   if ($images)
   		foreach($images as $image) {
   			$attachment=wp_get_attachment_image_src($image->ID, $size);
   			?><img src="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> /><?php
   		}
   }

   Unfortunately that is something I don't know how to do. I can take a look and try a few things, but it will be a few days before I can get back to you with anything.

   OK, I've got it. Replace the following:

   <img src="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> />

   With:

   <img src="<?php echo $attachment[0]; ?>" width="<?php echo $attachment[1]; ?>" height="<?php echo $attachment[2]; ?>" />

   According to what's in the WordPress documentation for the wp_get_attachment_image_src() function, that should work. Let me know if it helps!
