Hi there! Yes, you can use CSS and basic WordPress functions in a child theme to do this. I recommend using Firebug for CSS work–makes it much easier.
You’d want to target the wp-post-image class in your child theme’s style.css and set the border-radius property to 0.
To make the featured images larger, you’ll need to create a new functions.php file in your child theme and overwrite set_post_thumbnail_size() with the dimensions you’d prefer. Hook this into after_setup_theme like so:
child_theme_thumb_size() {
set_post_thumbnail_size( '150', '150', true ); //change the values to whatever dimensions you want
}
add_action( 'after_setup_theme', 'child_theme_thumb_size' );
To add them to the archive pages, you’d look at the code in index.php for adding the post thumbnail, then copy and paste that code into a new copy of archive.php in your child theme.
I haven’t tested this, so you may need to play around with it a bit to get it to work for you.

Thanks. I got the thumbnail sizes. However, I cannot find where you added post thumbnail in index.php since the functions used in index and archive are basically the same
get_template_part( ‘content’, get_post_format() );.
I added the code the_post_thumbnail( ‘post-thumbnails’ ); before that line so the thumbnails showed but they are too small and out of boundary.
Can you suggest something about it?
Ahh, check in content.php, and add the code in a child theme’s copy of content.php.
