I am designing a magazine style theme and I want different image sizes as to show on
index.php page. Now for this, I am using
<?php the_post_thumbnail( array(100, 100) );?> but it is picking 150x150 images not 100x100 images. So How to pick my desired different size of images that are uploaded before not after the theme using?
Note: My default media setting in WordPress blog is 150x150, 300x300, 1024x1024 respectively for thumbnail, medium, large.
