[Plugin: User Photo] Cropping user photos in square thumbnails

I needed this too and so edited some code in the plugin. Thought I’d share with others looking for such a solution too.

In the user-photo.php file at line 852, comment out this whole chunk of code:

// figure out the longest side
		if ( $info[0] > $info[1] ) {
			$image_width = $info[0];
			$image_height = $info[1];
			$image_new_width = $maxdimension;

			$image_ratio = $image_width / $image_new_width;
			$image_new_height = $image_height / $image_ratio;
			//width is > height
		} else {
			$image_width = $info[0];
			$image_height = $info[1];
			$image_new_height = $maxdimension;
			$image_ratio = $image_height / $image_new_height;
			$image_new_width = $image_width / $image_ratio;
			//height > width
		}

		$imageresized = imagecreatetruecolor( $image_new_width, $image_new_height);
		@ imagecopyresampled( $imageresized, $image, 0, 0, 0, 0, $image_new_width, $image_new_height, $info[0], $info[1] );

In its place, put this code instead:

// cropping into square thumbnails
		$new_w = $maxdimension;
		$new_h = $maxdimension;
		$orig_w = $info[0];
		$orig_h = $info[1];

		$w_ratio = ($new_w / $orig_w);
		$h_ratio = ($new_h / $orig_h);

		if ($orig_w > $orig_h ) {//landscape
	   		$crop_w = round($orig_w * $h_ratio);
	   		$crop_h = $new_h;
		}
		elseif ($orig_w < $orig_h ) {//portrait
			$crop_h = round($orig_h * $w_ratio);
   			$crop_w = $new_w;
		}
		else {//square
	    	$crop_w = $new_w;
	    	$crop_h = $new_h;
		}

		$imageresized = imagecreatetruecolor( $new_w, $new_h);
		@ imagecopyresampled( $imageresized, $image, 0, 0, 0, 0, $crop_w, $crop_h, $info[0], $info[1] );
