Bugs in thumbnail and LP Profile

Hi,

Great plugin. However, there are some bugs:
1. Thumbnail display: (a) Thumbnails cannot be removed from the Courses page, (b) Thumbnails cannot be re-sized, and will run into the search box (c) A null featured image will return a ‘NO IMAGE’ header for the course.

2. LP Profile: When clicking on the profile of a user, I get the following error: “Fatal error: Call to a memeber function get image() on a non-object in /home/mysite/public_html/wp-content/plugins/learnpress/templates/loop/course/thumbnail.php on line 19

On a separate note,

Is it possible to:
3. Hide the display for Student Enrolment in the courses page?
4. Hide the LP Profile?
5. Remove the “Free” display on the courses page for free courses.

Thank you.
