Detect duplicate image

Hi folks, today in this tutorials I am going to show you how anyone can easily detect duplicate image inside the page and remove one of them. I am writing this tutorial because recently I have been working in a inbuilt wordpress project where the content and images was already loaded. My job was to create a new theme with existing content. When I import those content in the new theme I found that in all post there were same image repeating. One is coming from feature image and another one was hard coded inside the page. Both the image was coming form the same path. With trying with some simple jQuery script I was able to accomplished this job.

This is how I detect duplicate image with the help of jQuery.

Detect duplicate image with jQuery

    var srcs = [],
    $("body img").filter(function(){
        temp = $(this).attr("src");
        if($.inArray(temp, srcs) < 0){
            return true;
        return false;

I hope you find this tutorial helpful. Thanks for reading.

conditional statement featured image

WordPress featured image allow you to upload an image inside your dashboard post and pages. The featured image box is usually on the bottom right corner(may be you need to scroll down to see the box when you land to add new page).
Sometimes we don’t have feature image and our area for the feature image remain blank. In this tutorial I am going to show you how we can use conditional statement featured image to fill up the area in the absences of Featured image.

Conditional statement featured image

Copy below code and paste it inside the function.php of your theme folder.

function catch_that_image() {
global $post, $posts;
$first_img = '';
$output = preg_match_all('//i', $post->post_content, $matches);
$first_img = $matches [1] [0];

//no image found display default image instead
   $first_img = "/images/default.jpg";
return $first_img;

Now go to the loop page where the feature image is displaying.

<?php if(has_post_thumbnail() ) { ?>
<?php } else { ?>
<a href="<?php the_permalink();?>">
<img src="<?php echo catch_that_image()?>" alt="<?php the_title();?>" />
<?php } ?>

Hope it helps. 🙂
