在WordPress的博客页面上显示博客图像的问题

Question

i am having a blog page in my website... There are different posts ... on left side blog image is displayed , on right side text is written..when i click on particular blog, the main page of that post appears with image on the top and text down the image. The issue is that on my blog page the left side images are not displayed rather default image is displayed.. bt when i click on post.. the main page of that particular post is having image...

 <div class="blog-img mainimg" style="">
<?php $blogmainimg = wp_get_attachment_image_src(get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' );?>
<?php if($blogmainimg[0] == '') : ?>
<img src="<?php bloginfo('template_url')?>/images/Noimg.png" />  
 <?php else : ?>
<?php the_post_thumbnail(); ?>
 <?php endif; ?>
 </div> 

only "if" is working.... else is not working on blog page, all the posts are having NOIMG.png.. which is wrong

???

Let's try a more simplified solution. This uses the has_post_thumbnail() to check if a featured image is specified, since you really do not need to utilize the wp_get_attachment_image_src() in the provided code.

<div class="blog-img mainimg" style="">
    <?php if(has_post_thumbnail($post->ID)) : ?>
        <?php the_post_thumbnail(); ?>
    <?php else : ?>
        <img src="<?php bloginfo('template_url')?>/images/Noimg.png" />  
    <?php endif; ?>
</div>

This uses has_post_thumbnail() to see if the post has one specified, if it does, it will display it uses the_post_thumbnail(). If not, it will revert to the default.

If this doesn't work, than it could be an issue of using the_post_thumbnail(), this would mostly depend on your loop that's displaying the blog posts. If that is the case, try this:

<div class="blog-img mainimg" style="">
    <?php if(has_post_thumbnail($post->ID)) : ?>
        <?php echo get_the_post_thumbnail( $post->ID, 'single-post-thumbnail' ); ?>
    <?php else : ?>
        <img src="<?php bloginfo('template_url')?>/images/Noimg.png" />  
    <?php endif; ?>
</div>

If this still does not solve the issue, please post the loop for your page as well, and I can further troubleshoot it.
