Image Size Change & Course Content Page Title Change

– COURSES OUTPUT PAGE > How do I change the image size on the Courses page to the size that I need. Right now the courses images looks like a triangle, but I would like a different size as per my specific image size.

– COURSE CONTENT > How to not show the “Exercise Files” on the content page when there is no attachments. Example, it’s a great function, but if there is not any attachments, this section should not show up. How do I deactiave this so that it doesn’t show up.
— Also on Content page, if I have for Example Lesson 1, with several chapters under it, then the first chapter doesn’t show the title of my chapter, it shows: About Lesson. How can I change it so that instead of About Lesson, it shows the heading of my chapter for my lesson?
— Also on the Content Page, the reader has to scroll to the top to “Mark as Complete”, while it would be more practical to have this at the bottom close to the Next button so that if the lesson content is long, the user will forget to go to top to mark the lesson. Also, it might also be more practical that user don’t have to use “Mark Complete” at all, rather when they click “Next” to go to next section, it automatically records the progress and mark as complete?
