Background: I am working on a theme using the WordPress 3 "Set Featured Image" function to display thumbnails on a category page here.
However the image displayed is actually the full, original size image with a smaller width and height setting, causing the page to download slowly.
I am calling the image via:
<?php the_post_thumbnail(); ?>
Question: Are there additional settings or coding so that the image called is the WordPress-resized thumbnail (imagename-150x150.jpg instead of imagename.jpg)?
