Reply To: Image is smaller when caption is used

[Tom]

WordPress sets a fixed width to images with captions.

You could try something like this:

add_action( 'after_setup_theme','generate_change_caption_padding' );
function generate_change_caption_padding()
{
    remove_filter( 'img_caption_shortcode_width', 'generate_remove_caption_padding' );
}
