He doesn′t answer me about a only function that anull this line. ??

In thumbs.php

function add_image_thumb($content) //add thumb in the begining of the post
{
global $post;
$img = get_post_thumb($post->ID,680,230);
if($img[‘show’] != false) {
if($img[‘src’] != “”) {

$img = ‘<span></span>‘;
return $img.” “.$content;
} else {
return $content;
}
} else {
return $content;
}
}

function get_first_image($post_id) { //retrieves first post attachment, check if is image

$args = array(
‘post_type’ => ‘attachment’,
‘numberposts’ => null,
‘post_status’ => null,
‘post_parent’ => $post_id
);

$attachments = get_posts($args);
if ($attachments) {
foreach ($attachments as $attachment) {
if(is_image(wp_get_attachment_url($attachment->ID))) {
return wp_get_attachment_url($attachment->ID);
}
}
}

return false;
}

in resize.php I can see:

<?php

/**
* Resizes an image and returns the resized URL. Uses native WordPress functionality.

* Images are saved to the WordPress uploads directory, just like images uploaded through the Media Library.

I am using TrendyBlog theme

I don′t find this function, but I am searching.

Yes! I work with Child Theme, the problem is… the author say me… remove this line in all files! But it is too changes.

And I think that this problem is possible fix it by other via.

This line resize all my images 500×500, but i don′t want it. I don′t want because I don′t use this size.

$image = get_post_thumb($post->ID,500,500);

For example:

<?php
wp_reset_query();
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) {
$my_query->the_post();

//categories
$categories = get_the_category($my_query->post->ID);
$catCount = count($categories);
//select a random category id
$id = rand(0,$catCount-1);
$titleColor = df_title_color($categories[$id]->term_id, “category”, false);

$image = get_post_thumb($post->ID,500,500);
?>
<div class=”col col_4_of_12″>
<!– Layout post 1 –>
<div class=”layout_post_1″>
<div class=”item_thumb”>
<div class=”thumb_icon”>
” style=”background-color: <?php echo esc_attr__($titleColor);?>”><i class=”fa fa-copy”></i>
</div>
<?php
if(df_get_option(THEME_NAME.”_show_first_thumb”) == “on” && $image[‘show’]==true) {
?>

And if I prefer don′t use plugin? Is there other option?

Sorry
