How to add size parametr to img?

Question

How can i add size parameter to my wordpress image?

The code i use for thumbnail is:

if (has_post_thumbnail())
{
    the_post_thumbnail('full');
}

I simply want to change url of image from

<img src="website.com/wp-content/uploads/img.jpg">

to

<img src="website.com/wp-content/uploads/img.jpg?size=10">

Answer 1

Use get_the_post_thumbnail_url() to get only URL of post picture and create an <img /> tag with this URL.

if (has_post_thumbnail())
{
    echo '<img src="'.get_the_post_thumbnail_url(null, 'full').'?size=10" alt="" />';
}
