The WordPress function image_resize_dimensions returns false on failure. The code in /includes/resizer.php on line 101 attempts to read from the function result with the assumption that it worked. If that function fails, the notice message PHP Notice: Trying to access array offset on value of type bool in is raised.
Later on in line 105 there is a correct check for function failure.
This patch moves the array access later when it is safe to assume that the function has returned an array value.
